I am having tongue issues with my cham. For the last 2 weeks or so he has just been sticking his tongue out only about an inch and can never get his target. He his not cup trained (believe me I am trying) so I have been feeding him by holding the feeders with tongs and letting him just get them that way. His hydration is fine I supplement D3 every other day multi vitamin twice a month and calcium with out d3 every other day. I gut load with carrots, potatoes, apple, grapes, lettuce and other greens. I noticed today a small yellow bump forming on the side of his mouth so maybe he has a mouth infection from eating something? Could that be what is effecting his tongue? Also on a side note when I sprayed today he rapidly drank with his tongue like a dog for about 2 min straight, just guzzling all the water he could. I have never seen this before today. He drinks fine everyday I mist 2 to 3 times, and his eyes are very bulgy and his crest looks great. The only thing wrong is his tongue. He does not eat some time because he gets frustrated from it, do you think its time to go to the vet?
