It funny you say that because yes Simba (the cat) Eats the dog food and Maybell (the dog) eats the cat food. Simba refuses to eat cat food. Maybell is the only dog that eats the cat food and she also eats out of the litter box. I been trying everything to stop Maybell but nothing has worked yet.I may move the litter box to the bathroom and shut the door because the cat goes under the doors anyway but that will only be good for a little while untill the cat gets to big to fit under the doors.
Most dogs, given a choice, will prefer cat food. But it's not good for them to eat it on a regular basis.
Same thing for cats-dog food does NOT have the necessary nutrients for a healthy cat.
I keep litter pans in the basement. The dogs don't go down there, and it's also a safe haven for the cats. Cat food is both in the basement and on the kitchen counter-again, inaccesible to the dogs.
I spend a small fortune buying good dog food-I am NOT going to waste it on the cats when it's not what they need, and I am NOT going to allow the dogs to eat from the litter pan! If I were going to do that, I might as well just feed them Old Roy.
The average dog is a nicer person than the average person.
My first kitten ended up with really bad diarrhea from helping herself to dog food. (aka big vet bill) I had to buy elevated food bowls for the dog to keep my kittens out of it. Then the third kitten learned to stand on her back legs and fish around with a paw in the bowl until she knocks pieces out to eat. So I have to watch Max and make sure he just finishes his food now. And for the cats, I set their bowls up in a corner with the cat tree blocking his access so the dog won't eat theirs. Theirs is just too expensive for the big oaf to keep eating all up on me.
Ugh! I missed the litter box comment. If your cat will use a covered box, try turning the opening toward the wall so the cat can get in but the dog would have to work at it to get a "snack".
Catfood contains a nutrient essential to kitty's vision, especially her night vision. It is really important that kitty gets it in her diet. Do whatever you can to get her off the dog food. Nursing from the dog won't hurt her though, in fact it's probably better than kitten formula since it is all natural. Catfood is not made for dogs, but I've never had a dog get sick from it or anything. It is higher in protein. Maybe you could feed them both cat food, but I would ask a vet first, bacause I don't know a lot about dogs.
The cat probably does think its a dog. I had a kitten that was raised with a puppy, she would hike her leg to pee and everything. It was too cute.
As for the litter box thing, eeeeeew! Gross! sorry I don't have any useful advice on that one.
I like most cats better than I like most people. I'll try to be nicer if you try to be smarter.
