My Florida Blue garter used to eat just fine. I've had him since he was about 6-7 inches long and he's been a champion eater ever since. He eats 3-4 night crawlers once a week. However, within the last month he hasn't eaten. It isn't for lack of wanting or trying. I put the worm in his habitat and normally, he powers the worm down in less than 30 seconds. But, now, it's like he can't get a hold of the worm with his mouth very well anymore and he struggles to keep hold of it. It's like he's lost jaw strength and then the worm gets away. He tries and tries until he ends up giving up. Does anyone know why this would be happening all of a sudden?
