How can I get my cat to stop biting his own foot until it bleeds?

[angels_angelsarehere765]

perhaps his foot has an inner irritation that only he can feel (like when a body part gets numb from being in one position to long) Bath his foot in Tea Tree soap or shampoo Then rub/massage Tee Tree oil on it By a pair of newborn baby socks put it on his foot. Wrap with surgical tape,the entire foot sock and all, then put the other sock over that.
Change and wash the foot. at least at least 3 times a day.
I hope it works
