Trust me when I say that this is embarrassing for all parties involved, but this weekend we bought Maxwell a cat leash. He has been an indoor kitty ever since we took him in back in 2005, (thinking that he was a homeless, pregnant, female cat -- it turned out that he was just a homeless, (and over fed by all our neighbors) fat, male cat....w/ large nipples...). Anyway, we care too much about this guy to have continued to let him roam the streets of South Everett.
It doesn't change the fact that he REALLY wants to be outside - particularly eating grass and sniffing around where the other, "free" cats roam.
So far, the leash works great :) He doesn't seem to want to go too far, and we can just sit out back and let him do his thing (eat grass) without fear of him bolting.
