It is on the back leg one pad off to the side, he was limping this morning and when I picked him up he bit me, uncharacteristic of his mellow temperment, so I brought him under a bright light and examined him. There is a portion of the pad missing and a hole dead center in the pad. I am thinking he and that %^%$$%&&**(*!!! feral that I can't catch decided to dance last night, and he lost the dance ticket. I have never had more trouble in trapping a feral in my life as I have with this new one "Mobster" who has been hanging here for almost a month now. I am seriously considering having a wildlife gal I know come over and dart him, but even that is tough, because I hardly ever see him.
Thanks for the advice Sandie, I have a supply of baby socks I use for times like these, but it is hard to keep them in place once a disgruntled cat decides he doesn't like to be dressed up in baby clothes!
