I had 2 wandering garters last night, never had I seen canibalism before, but I had kept my snakes in a larger enclosure.
What I know:
-The snake I'm left with was the biggest, she's just shy of 3 feet.
-I heard some sort of ruckus last night, but assumed it was the bullsnake moving around or the nile being rascally.
-The other snake was 24 inches long, but also had a tendency to climb a little bit.
-The snake I'm left with looks slightly bigger, and wasn't fed within the last couple days (a big fuzzy that left no visible signs on the snake, and the fuzzy was thicker around than the lost snake)- Was fed I believe 3 days ago.
-The last snake in there is extremely active, moving around a ton and being a bit feistier than normal, and she feels different.

I'm thinking just cannibalism at the moment, looking at the other snake, and that is honestly what I'm hoping for, seeing as though my mother hates snakes and would kill it... They are kept in 30 gallon rubbermaid containers with locking lids on all 4 sides. I'm fairly certain if the big bullsnake couldn't press through the locks the little one could.

Any ideas would be appreciated, I'm at a loss for what to think atm
