Hey there.
So I have my male Corn for like a year and half, he was the most calm and docile snake I have ever met until yesterday feeding.
He mimic that poison snake with his tail, went up with his belly at the S shape and strike the rodent few times- not to eat, just aggressive.
Even today when I walk past his cage he moving his tail fast like a warning sign.
I had him few days after he hatch, his 1.5 years old male albino corn snake.
Maybe the hormones? The weather outside getting warm.
P.S=- I know its not good but for the past 2 month's he had no warm side, the cage was around 77F all day and night.
