I kinda like cats, but I'll never have one in the house.
Both cats
and dogs stink. Especially the males that like marking their territory.
My allergies don't help, either. I can stand to have one on my lap and pet it, but once I touch my nose the sneezing starts and it's history. Likewise, I can't stand going to cat lovers' homes that don't know when it's time to vaccuum up the hairballs.
