I am very sorry to read this. I haven't been able to bring myself to post here, although I've tried several times. Tomorrow will be 3 weeks since I had my Morgan put to sleep. He too had an oral cancer. His was a tumor on his upper jaw. I still have tears thinking and talking about him, but it is getting easier each day. I miss him terribly, and I'm sure you'll deal with similar feelings grieving for your dear kitty. I hope you can find some comfort from the words and thoughts posted here and in the happy memories that you carry with you.
