Bobert, I'm glad she's feeling a bit better. Sometimes you just have to grieve. It would probably be easier if she knew for sure that Timmy was gone.If Timmy is gone for more than a couple of months and you never know for sure, a memorial might be a help to let her let go. Maybe a little ceremony at home or a memorial donation to an animal rescue group like Best Friends Animal Sanctuary.
If I want to attract cats, I just smoke some salmon. I bet 4 or 5 cats show up in a few minutes... one might be yours!
