My first thought was “Well color me stupid”.
I was checking the security videos to see if Sophia had visited the barn earlier today and there was Tabitha eating in the barn. The only problem with that is that Tabitha is in my basement ready to have kittens at any minute. When I pulled up pictures of both cats, I could see that the pregnant kitty in the basement was a new one. They’re both long haired grey tabbies, but there are differences in the faces. Though I’m disappointed that I didn’t catch Tabitha, I’m happy that the new one will have her kittens in a safe place. Now I have to come up with a name for her. I’ll call the local animal shelter to see if someone has reported her missing.
