Gee, I sound awfully mean -- I'm really not - I will stop and feed animals that are hungry and people have dumped out -- I just don't bring them home anymore.
It's your choice whether to have pets in the house or not, obviously. But your post is unclear -- do you not have them in the house simply because they make a mess, or is it because you are allergic to them and/or have an asthmatic response to them?
