I think as long as you can take care of the animal and carry it to the vet when it needs to be carried then it's ok to have as many animals as you want. We have 3 dogs, 3 cats, 10 ducks, 3 birds, 1 rabbit, 1 goat and some fish right now. But, I think as long as the animals get what they need then it's alright to haev as many as you want.
