Too small prey item?

[rabernet]

There are also just as many people who have snakes that go off feed during winter.

I am convinced from my own experiences and conversations I've had with Adam about my observations that 90% of the winter fasts are husbandry related:

Enclosure too large
Temps not stable, even a degree or two drop at night combined with shorter days can throw them off feed
Overfeeding
Overhandling
Hides too large
