Genia,
You know, Misery loves company. Get the cat! We have two rather large dogs, now two cats, two hamsters and three hermit crabs. And my daughter asks for more all the time!!!! I thought I was at my limit until Butter came along. Taking in a cat is easier than another dog (which I considered when I found a stray a couple of months ago). Thank goodness that black giant found a good home with one of my friends.
