Suriname Red Tail Boa - Suddenly aggressive

[Myshaele]

Greetings everyone,

I've had my girl for 2 years and she's always been amazing; we carried her around, manipulate her all the time with no problem whatsoever.

Suddenly, last week, she became aggressive; I opened the vivarium, as usual, to pick up a little piece of shed skin and she just launched and snapped me for the first time in 2 years. The next day, I fed her 4 big mice and she snapped at them as well, which she only did once in 2 years. She has always been shy about feeding and would wait at night to do it.

Today, I opened the viv again and she snapped again, following me around, moving around to make sure she would not miss me.

What could be wrong? We did not make any changes at all in her vivarium, it's kept clean, the water is fresh and changed often, the temperature and the humidify are controlled, she has a huge bath to rest in, a fountain, a huge hollow trunk to hide in...

I'm clueless and suddenly afraid of her, which I don't like.
