His temps are between 68-75 tops!
Humidity is normally 60-70%
He eats regular and is a varied died, I dust his food every feed and dust his food with d2 2 times a month.
I think his temps are too low.
He is a nosy b panther make and is 5 months old.
Is he still doing it today? I would agree that generally they sit with their mouth open because of temps being too high. If he is still doing it today I would try to get a look inside the mouth area and see if there is more to it than just temps.
I know you guys won't agree but I have 2 sticky thermometers and and exo terra digital reader and another I branded digital reader off eBay and I use them all to cross reference!
Any ideas would be cool! He has made one of two wheeze sounds but it could be low temp and possibly a cold as he is well aerated and some of the cold night etc
