Weird behavior

[Gio]

Have you been experiencing springlike weather in your area? In the last two weeks a lot of my snakes have gone from being ho-hum about eating to stupidly foody.

Also if your boa is 1050 grams he should be able to take a small f/t rat.

Exactly.

Boa constrictors respond to seasonality whether you create it or it is real. There are subtle changes in pressure, climate, humidity and also daylight hours that will bring about activity. Your boa is probably experiencing the climate variation.

If all other health and husbandry aspects are in check I'd bank on the weather changes.

You boa is not an adult that is fully grown so you could also upsize prey. My boa doesn't eat from November until late March or early April but he is fully mature and that is a very normal cycle. A younger boa will eat more frequently.
