Hello everyone, This is my first time posting in a reptile forum. I have owned a Kenyan Sand Boa since Nov. 2015 without any major issues. However, lately he has been exhibiting some odd behavior, so I was hoping someone could give me advice. Some background info: Kenyan sand boa Sex unknown Adopted Nov. 2015 Age unknown (supposedly 2 years old at time of adoption, but was way too small so I suspect that info was incorrect) Currently 20 inches long, 6.7 oz (about 190 grams) Currently eats 1 thawed hopper every 2 weeks Last shed about 2 weeks ago Last fed 4/29 Tank set up: Reptile sand (he has always had sand) A cardboard box filled with Carefresh on the "cool" side of the tank Water dish Fake log (sometimes gets rotated with other objects such as a wooden bridge or fake plant) Humidity hut (I know sand boas don't usually have one, but he's always had one without issue. He does like to hang out in it once in a while) Ceramic heat emitter & heat pad on the "hot" side of the tank with temperature probe, both heat sources are on a thermostat set to 90 degrees in the daytime and 70 degrees at night His tank has been basically the same for all 2 years that I've owned him. Usually my boa spends almost all of his time buried in the sand or Carefresh. For the past 4 days, however, he has been spending all of his time up against the tank wall, very strongly nosing around the top of the tank. I'm worried he might start damaging his nose by rubbing against the tank's metal mesh cover. When I open the tank, he's immediately coming over the wall, which is unusual because normally he tries to hide when a person is standing too close. In early 2016, he did a lot of climbing too, and at that time I started feeding him larger mice (pinkies to fuzzies), and this solved the problem at that time. I thought maybe it was the same problem again this time. I tried feeding him last night (a week earlier than usual), thinking maybe he was just too hungry again. He took the hopper at first, but when I checked on him later he had dropped it and was trying to escape from his feeding carrier. He ignored or actively avoided all attempts to re-offer the hopper. I'm not sure if the snake is male or female, but could this be a case of breeding behavior? Since we finally have some good spring weather in our area, maybe he's too hot? (Although the thermostat should be keeping the sand temp constant, and he hasn't been spending a particularly abnormal amount of time on the cool side). Otherwise I have no idea what's gotten into him. Nothing else in the tank set up or daily routine has changed.
