HHH - Very sorry to hear of your loss... I can't imagine not having my "Derby" cat (that where I got my screen name from), she is the sweetest Tortie ever (or so I've been told), she's aloof but will surprise me all the time. Last night I had insomnia and was up watching TV and she came and snuggled next to me and fell asleep under my blankets - that helped me finally fall back to sleep
My thoughts are with you and your Jitten tonight...
p.s. My other cat is "Jerry", named after Jerry Bailey... they're both a couple of showboats!
