I had a cat with my birds in my other apartment. Both apartments are one bedroom but this one bedroom is tiny. It was very easy to keep them separated. I would definitely like the company but I don't want to hurt Max in any way. I didn't hear from my sister today so I'm assuming that someone else took the dog. I'll tell her tomorrow that this apartment is just too small for both pets. If I eventually move and get a larger one bedroom than I'll probably get a cat.
