My cat has a colon problem or something, where crap just builds up inside her and about a year ago she had to get a clean-out sort of thing done, and it worked for about a year but she seems to need it again. My dad refuses to pay for the clean-out so he has been refusing to take her to a vet no matter how much I beg, so I’m curious if theres anything we can give her that might give her some energy in the meantime? We’ve gotten some cat milk in her and mushed some food into it for her, (she refuses to eat), but she’s still pretty weak and getting malnutritioned, is there anything I can give her temporarily til I convince him to go to the vet?

Sorry if this doesn’t make much sense.
And thanks in advance;.
I think it may be megacolon, on wiki it sounds like that but I’m not positive. If that helps.
