They can only make you feel bad if YOU let them! You're doing the right thing for both you and Lily. Ignore these people. Don't talk to them about your cats, it's obvious they're ignorant when it comes to owning one. You do what is best for you and Lily and forget what they say. Grrrrrrrrrrrrrrrrrrrrrrrr.....I have this problem at work. They think it's funny to try and upset you. Please don't let them do this to you.
