None for me anymore... as much as I'm gone it just wouldn't be fair to them, and too many predators where I live to leave one outdoors. I had one old cat for 18 years though, and just couldn't deal with stuff after that one was gone, so I adopted Slick. He was a great cat... a real sport. Had no vices, none of the guile or wiles one expects. He was extremely suspicious of ceiling fans, and I am too, so we understood each other. Alas, Slick found himself a better gig somewhere else. At least that's what I hope happened.
These days, I just throw the ball around for Mom and Dad's dog, Zelda.
