that ' s good to know . Do either of them allow you to change the key word ? Do either of them allow setting up custom phrases for custom functions ? <| sep |> That ' s odd , I have three cats and one big litter box . One of them prefers to go outside , but if no one is home to let her out she uses the box . I understand that they can get territorial , but the two who only use it use their own designated sides that they decided on . I also clean it out every morning . The only problem I had beyond the actual training part is that the boy is a bit of a beef cake 17 pounds and not overweight and hates sitting in the box to poop so he perches on a corner . I had a small litter box from when they were babies and that thing got tipped over like no tomorrow when he ' d perch , which scared him and made him start pooping next to the box instead . I bought one of those giant multi cat ones and it hasn ' t tipped over since .
