One of my two cats has a disease that requires him to eat a special diet , which I feed to both cats out of convenience , since there ' s no reason the other can ' t eat it too . When he was first diagnosed , there was only one brand of food at my vet that fit the special diet . And frankly , it was a downgrade from what they had been eating , in terms of fillers and nutrition and so on , but I needed it to keep my cat alive . Then my vet informed me that another company had started making food for that special diet and that it was high grade food on par with what I used to feed them , so I made the switch . Aaand shortly after I moved and realized that the local vets in my new area hadn ' t started stocking that food yet , and since it ' s prescription food , it ' s incredibly hard to get and very expensive outside of a vet , so I couldn ' t just get it on Amazon without spending a buttload of cash and honestly , the food is already expensive offline , so making it even more expensive is just insane . Soooo any time I have to go back to where I used to live an hour and a half away which is where my parents and sister still live , but I try to avoid visiting because my parents are toxic , I buy a bag . Or two . Maybe I should buy three next time . So far I haven ' t run out of it . When I do , I may have to switch back to shitty fulloffillers cat food , but I ' m hoping not .
