So i have a boa i got from a friend and ive only had it about a week now but I've noticed that when im moving around he watches my every move like really watches and if i change his water he always comes to the opening to see whats going on
Thank you for your question. This is normal behavior for many species of snakes. Remember, boas can be ambush predators and movement of any kind attracts their attention. Also, because snakes have to be aware of any animals that may prey on them or large animals that may step on them, again, they are very aware of movement around them. So, if you're moving around close to the snake's enclosure he/she will watch you. If you lift the lid of the snake's enclosure and put your hand inside the cage you will generally attract the snake's attention. Over time, your snake may become accustomed to routine movements and stop watching so closely.
You didn't indicate the size of your boa in your question. One issue to be aware of is feeding your snake in its cage. If fed inside their cage, some snakes develop the habit of approaching their owner anytime they see the lid of the cage lifted or removed, because they come to associate that movement with food. If your snake is still small, you can remove it from its cage, place it in a smaller enclosure and feed it there. After it has swallowed its food and settled down, you can carefully place it back in its primary enclosure.
