Thanks for your reply, I'm a bit late, busy weekend
Yesterday I closely watched him and after giving him extra calcium and vitamins we noticed now it's a serious infection. His tongue is so thick and weak he's almost choking!
My boyfriend is taking him to the vet today. I'm only there in the weekend at the moment so thats hard for me...Wish I could do something..
Anyways, his tonque is really really red and it's just a piece of flesh right now that he throws out of his mouth all the time to be able to breath.
Hopefully it can be solved with anti-biotics or desinfectant, hope he will be ok...Would be devasted when he would die or loses his tongue..
