Hello everyone. I have recently acquired a 3 year old corn who is healthy in every way except he is very nervous. He shakes his tail when i try to pick him up and he also makes a sqeaking noise. You may say its probably a hiss but it really sounds more like a mouse squeaking than a hiss! Does anyone know if this is normal as i didn't know that corns made any kind of noise? Do you think he is just a bit highly strung or it is more serious and what can i do to make him less stressed? He lives in the same tank as a python and they seem to get on well but could this be anything to do with it? I feed them separately by the way. Also, i know this sounds very dumb but can snakes of different breeds mate with one another? I don't think they can but i just want to make sure as i don't know the sex of either of my snakes. Sorry for my lack of knowledge but i am just starting to get into snakes after a reluctant start. Hope you can all help!
