So, I have a kitty (Lola) a pet rabbit (Chicco) and a yorkie (Takis).
Lola often eats Takis' food and sometimes sits in Chicco's cage.
Chicco drinks Lola's AND Taki's water and sits in Lola's litterbox.
Takis eats Lola's food and that often causes him to throw up.
If they continue like that I'm afraid i'm going to have to sell/give at least one of them. And I can't do it

How can I train them??
Lola is 3months old, Takis is 1,5year and Chicco is 2-3 years old.
