Thank you!! His energy level is right back up to regular this morning after some hand feeding!! He and I thank you!!Here is a response I got about the tongue
The tip of the tongue looks discolored, but not necessarily wounded. I wouldn't consider it urgent, but probably worth having the vet take a look while he's there for the next visit. It could be bruised from pushing it against a syringe, and I'd imagine that would heal just like when we accidentally bite our tongues. There are oral cleansers available like MaxiGuard, but I don't know that it would be needed at the moment, but wouldn't hurt. I'd probably defer to the vet's advice.
I will send a proper pic/measurements of enclosure a little later for when the new light arrives.
Things are looking up- feeling grateful!
