Forest's hormones was going haywire this weekend!!! He was head bobbing continuously and made himself look very thin while walking on his tippy toes. He also patrolled the sliding door while wiping it with his tail quite aggressively. I also found him on the bed biting down on a towel and saw this protruding: I was totally shocked because I have never seen this before. I suppose it is his hemepenis, but what is the round part above it? It only showed for a short while and I did not see it again. Plus, Forest will now be 1 year and 4 months and he is 43 inches. I read that breeding season only really starts at 2 years and that there is definite color changes, orange or red. He is still completely green, there is absolutely no color changes, therefore, am I right in assuming that he is becoming a teenager now? I took this photo this morning, he is under a red light but you can see that he is still completely green. He is not really eating anymore and his tail looks fatter than usual. What do you call this stage that he is going through now, or can he really be entering breeding season already?
