There is no question that non pet lovers look at guys like us and think we are nuts or weak for feeling so bad when one of our little buddies dies, but we who do love them understand completely. I have sobbed like a baby when Scooter and Sniffy had to be put to sleep. I still tear up when certain things they did come to mind or I see a picture of them.
You are right that no other cat was like Toby, each one has their own personallity and funny little tricks. We have about 8 or 10 that come around to the shop every night and some of them become closer to us than others. We have had some come into the shop and have a favorite towel they like to lay on, or a toy they play with.
I guess the one thing all of us who have lost a beloved pet has to keep in mind is that for a while we gave him or her a safe, loving home and in return they made us laugh and gave us unconditional love.
