To start with - My red tail boa somehow injured and lost his tongue in January 2017. Still can't figure out why/how. Vet checked out and in good health otherwise. In the months since then he has eaten twice (1 jumbo frozen rat & 1 large frozen rat each time). He was due to be fed in early July but wouldn't eat them or any of the other 6 times I've tried this month. He's also been acting super active, rubbing his nose all over the screen lids and glass and even mouthing at the glass. His eyes are clear, gums look good, no eye caps left on or bad shedding, and he's peeing and pooping regularly. Has anyone heard of this happening before? At what point should I be worried? On a side note - I moved to a new apartment a few months ago and his cage is now in a more central area that gets a lot more natural sunlight in addition to his uv and ceramic heat lamps.
