Do older collared lizards eat less?
We had a pair of Collared Lizards for 4 years. We just recently lost the female to old age and cold like symptoms. The male is still alive but acting more and more feeble. We used to feed them crickets, but he is so jumpy and would often fall on his back after attacking the cricket. Now we have started feeding him super worms instead. He only eats one or two a day. He isn't very active, and he is very defensive when we try to pick him up. He even bit me once which he never used to do. I feel for him, but I don't know how older Collareds act and if this is normal.
