DON'T FEEL GUILTY!!!! id never make my mom or even step mom(which i don't have thankfully LOL... i got a step dad though) feel guilty and make take on my animals. they are not your responsibility. they are hers. she needs to find a place for them.. and that doesn't mean your house. she needs to realize that life is hard and she needs to deal with it. she needs to grow up and realize life isnt' always fair and she doesn't always get her way. she thinks she can just pawn these pets off on someone and expect to get them back later? hmm. i don't think so. you and your new kitty deserve time together.
