I know this sounds a bit "dangerous" but what about trying to massage his tongue a little bit to see if you can help stimualte the nerves in it. I wish you could get off to a vet and see what they say before you get to much more attached to him..

I don't see where having to hand feed a cat or cleaning one would be that much of a problem and I am sure there are more out there that feel that way too....IF he never gets the use of his tongue back, but I would be wanting to see what a vet said about about one with no use of it and the problems related to it...

I just can not believe it survived with all that gook in it's mouth and hole in it's chin. He sure is a little fighter, he fought to stay alive until you came along to help him.. Thank GOD you did!!
