i got a horsfield tortoise and yesterday he started acting strange. he starts opening and closing his mouth then he gets those big eyes and starts trying to scratch them then starts breathing heavy and putting his head in his shell.. iv only seen 1 bubble come out of his nose since it started so i dont know if its an early stage of the respiratory problem. his nose isnt wet or anything... if i need to take him to the vets how much would they charge? also i live in teeside and dont know of any reptile vets around here but maybe someone knows the closest? thanks
