So I got a baby sharp albino boa constrictor about a month ago. He ate perfectly normal the first couple weeks and showed no aggression but then he got strange. He would start by biting the mouse(f/t heated with water) and constricting it. But after he thought it was dead he would put it down. At this point I am about 3 feet away watching and he would watch me, if I moved or got to close he would hiss and strike. After I get out of eye shot he would start eating. Has this happened to anyone? Is this normal behavior?
