Good questions hun! I can't answer for you, haven't owned a cat as an adult, sorry. But you know, I think after owning one for awhile you would probably enjoy it, and really come to like having one. They are pretty nice to have around. I'm more of a dog person, but cats are good too

Oh, and I don't think cats should have milk, from memory. Our dog doesn't have any commercial dog food, her skin conditions mean she needs 'proper' food. I'm sure you could do the same for a cat Hopefully someone with more knowledge will pop in!
