referring now to the drawings , the structure of the invention which is illustrated therein includes a support means which is easily movable and which includes a plate 10 made of any suitable rigid material such as a suitable plastic , this plate 10 being fixed with vertical partitions 12 and 14 which divide the upper surface of the plate 10 into a number of compartments as illustrated . thus the partition 12 extends longitudinally along the center of the upper surface of the plate 10 while the partitions 14 extend perpendicularly from the central partition 12 to divide the space at the upper surface of the plate 10 into a number of compartments . the material utilized for the plate 10 and the partitions 12 and 14 may be , for example , a suitable synthetic resin which is inert with respect to natural secretions of the animal as well as with respect to products for disinfection and maintaining the animal . in the illustrated example the plate 10 is provided with feet 16 and wheels 18 , the feet 16 being situated , for example , at the regions of the left corners of the plate 10 while the wheels 18 are situated at the regions of the right corners of the plate 10 , as viewed in fig1 and 2 . thus , by reason of this feature it is easily possible to move the plate 10 and the structure carried thereby to the best possible location . moreover , a cover 20 is provided as schematically shown in fig1 . this cover 20 may be made , for example , of a transparent plastic . it has a top wall provided with a handle 22 . moreover , at the region of its lower periphery the cover is formed with a series of openings 24 capable of receiving the spring - pressed pivoted catch elements 26 which are carried in a known way by the plate 10 at the periphery thereof . thus , with an animal situated on the plate 10 it is possible to slip the cover 20 over the plate 10 so that the catches 26 will snap respectively into the openings 24 , and in this way it is possible easily to carry about the entire structure with an animal situated therein . of course the distance of the top wall of the cover 20 from the bottom edge thereof is adequate for the particular animal . in order to remove the cover 20 it is only necessary to depress a pair of the catches 26 such as those at the left in fig1 and 2 , and in this way the left end of the cover 20 can be displaced above the thus - depressed catches 26 , the cover having sufficient clearance with respect to the plate 10 for this purpose . then one or more of the remaining catches 26 can be depressed to enable the entire cover to be removed after the animal with the structure of the invention has been transported to a desired location . the several modules of the invention , as described below , are of a size which enables them to be respectively situated in the compartments formed at the top of the plate 10 by way of the partitions 12 and 14 . the plurality of module means of the invention can have widely varying configurations and purposes , and preferably can be designed to be utilized individually or in combination in a manner which will be apparent from the description which follows . thus , for example , one of the module means of the invention can be a &# 34 ; refuge &# 34 ; type of model formed by an enclosure 28 which is closed except for an access opening 30 through which the animal can conveniently travel into and out of the enclosure 28 . the size of the opening 30 is preferably made just large enough to permit entry and exit of the particular animal . this enclosure and its entrance and exit opening may be constructed in the manner of a niche or a cage for birds . in the interior of the enclosure there are provided suitable accessories for the comfort of the animal . thus , for example , in the interior of the enclosure 28 there is a cushion 32 having in its interior an electric heating element 34 shown schematically in fig2 connected into a suitable circuit having batteries 36 and a thermostat 38 as well as a switch 40 which responds to the presence of the animal on the cushion for closing the illustrated circuit and thus causing the cushion to be heated to the temperature set by the thermostat 38 . in addition , the interior surface of the enclosure 28 is lined with a sound - deadening material 42 which provides for sound insulation which will minimize noise in the vicinity of the enclosure 28 , the sound - deadening material 42 being particularly designed for preventing transmission of ultrasonic wave lengths to which the particular animal may be particularly sensitive . a further module means , which is not illustrated , may be similar to a nursery and provided with automatic feeding devices and other accessories of appropriate function as well as with means for protecting access to the module . an additional module means 44 is of the bodily convenience type , of benefit both to the animal and its master , and may include a receptacle 46 containing an absorbent material 48 and partly covered by a cover 50 having a central opening through which the animal has access to the material 48 . this cover 50 has a suitable rough upper surface 52 which preferably forms a scratch surface . thus this scratch surface forms a border surrounding the receptacle 46 . in addition there may be provided an unillustrated distributor of a deodorant product for the receptacle 46 . a further unillustrated module also designed for bodily convenience may include a reserve of food and / or beverage contained in a device designed to meter the supply of the food and / or beverage so as to permit access thereto according to a predetermined time program , thus facilitating an extended absence of the master without the risk of overfeeding on the part of the animal . as is shown in fig2 and 5 , a further module means of the invention fulfills the function of friendship and may be utilized in the case of absence of the master . this module means 54 includes on a suitable supporting plate 56 a recording play - back device 58 in the form , for example , of a suitable tape recorder which plays back the sound which is stored on a tape . when the animal places itself on the plate 56 the animal will depress a plate 60 which will close a circuit 62 schematically shown in fig2 so as to energize the recorder 58 which thus operates to provide for the animal the sound which is stored on the tape . this sound may be a program providing for the animal sounds and / or voices simulating a friendly presence . also , it is possible to provide a module means 64 which , as shown in fig2 and 6 , includes a container 66 having a perforated cover 68 and containing in its interior old linens 70 or other suitable material impregnated with the odor of an absent individual . the several module means of the invention also include an exercising module means 72 in the form of an endless band 74 guided by rollers 76 which are suitably braked with respect to the shafts 78 on which they turn , the endless band 74 being suitably inclined as illustrated , and if desired the inclination can be rendered adjustable in any suitable way . the surface of the endless band 74 is covered with felt , for example , offering a suitable surface to be engaged by the claws of the animal . a similar type of unillustrated module may include a ball or other solid decoy connected by a suitable flexible cord or the like to a spring mounted in a suitable socket . an animated type of module means of the invention may include the module means 80 shown in fig2 and 3 . this module means is formed by a stretchable elastic sheet 82 covering a suitable enclosure 84 in which there are a plurality of mechanisms in the form of plugs or projections 86 which move upwardly to stretch the sheet 82 when certain other projections 86 are depressed by the animal . thus a plurality of tiltable levers 88 may be supported on suitable pivots in the enclosure 84 and may carry at their ends the plugs 86 so that when one plug 86 is depressed the other will be raised to cause the sheet 82 to project upwardly in an uncontrollable and surprising manner . fig3 schematically illustrates a paw 90 of the animal depressing a part of the sheet so as to depress one projection 86 shown at the left of fig3 so as to cause the projection 86 at the right of fig3 to rise as illustrated . a further module of this general type may include the module 92 illustrated in fig2 and 4 . this module 92 includes a support plate 94 on which there is turnably supported by way of a suitable central pivot a circular plate 96 carrying a number of figurines 98 simulating different animals . thus , when the house pet engages the plate 96 or one of the figurines 98 , the several figurines will move past the house pet in a haphazard manner . in addition it is possible to provide any projections or the like which serve a similar function to the extent that the faculties of perception and intelluctual capacity of the animal permits . finally , a module to be utilized all the time by the animal and which is ornamental with respect to the apartment or house may be formed by a house garden or the equivalent thereof planted together with a grassy type of covering . the several examples referred to above of course are not exhaustive but on the contrary serve only to show clearly the entire concept and combination forming the object of the present invention and serving for all adaptations and accommodations which can contribute toward pleasant cohabitation with a given animal of known or predictable habits in a particular living framework whose primarily artificial character is at least partly minimized by way of the present invention . in effect , the modular nature of the integrated assembly of the invention and the variety of the modules which can be utilized assure the precise adaptation of the assembly to the capacities and needs of a given animal . a further advantage of the structure of the invention , relating to its transportable character , is that it avoids any trauma with respect to separation of the animal from a given environment in the case of permanent or temporary removal from a given abode . yet another advantage of the structure of the invention is that it may structurally evolve to the same extent as the growth of the animal . finally , and above all , the structure of the invention has the advantage of providing a solution to the conflicts inherent in modern life as a result of the artificiality thereof , while fulfilling the desire to possess a house pet while providing for the house pet at least partially the impression of living in a natural environment . it is of course to be emphasized that this advantage is of benefit not only to the animal but also to the master .
