[[tldr; My vet tells me he recommends a shot of Depo-Provera for my iguana's breeding season behavior. Thoughts?]] Hi everyone. I haven't been on this forum in years, but stopped by back in 2011 when I first adopted my iguana. I recently moved to Florida and got a new vet. Some backstory on this vet... They have two green iguanas, both male, both in cages attached to the windows of the vet office, but next to each other (with a divider, but they can see each other). I don't like this, for obvious reasons. They do feed them greens, but mix pellet food in. Another point against them. When I was there, they were both sitting well-behaved, but one had scratched his nose up (not surprised.) I brought my iguana, a male (age is guessed to be 8 years) in for a checkup after I got back from visiting my family for the holidays. While I was gone, his timer got bumped (it is one of those timers where you push in tabs for the hours you want it on) and the pet sitter didn't notice, so it was on longer than normal. The first night I got back, he was awake the whole night (I know this because I had stomach flu and was up all night) and his light had been changed to coming on and off almost every half hour throughout the night (obviously, I changed it back to normal when I got home). The next day, he was chasing me around the room. He was not doing an aggressive 'crab-walk' like he does around my brother, just following me around and occasionally sort of scuttling after me. He wouldn't actively try to bite me, but sometimes will half-heartedly go after my leg, but not charging or anything outright aggressive. I told my vet this, and he said the photoperiod being too long caused him to be aggressive. He told me to put my iguana somewhere dark and give him 4 hours of his light per day for a week. Usually, he gets real sunlight out on our patio, but I brought him in for his fake bake about a month ago so he could get used to being inside for when the pet sitter was here. Anyway, that was on Monday, and apart from taking him out to use his poop box, he doesn't get to come out of my walk-in closet. I don't like this arrangement and he is still behaving the same. I got him a stuffed alligator as a 'toy' to take his sexual frustration out on. He seems scared of it, though, so I'm not sure. The vet said this was a bad idea but, like I said... I don't trust this vet. Anyway, the main reason for my post here is that my vet said he would give my iguana a shot of Depo-Provera if his behavior doesn't improve. He said this helps with the aggression, but I can't find anything about this online. Yet again, he also said neutering works on young male iguanas, and I'm pretty sure the consensus on that is questionable. In short, I don't trust my vet and am looking for opinions on this. This is the first year my iguana has behaved this way, and I am not sure what to do. I hesitate to authorize a progesterone injection like the vet recommends. What do you think? Have you ever heard of this?
