Earthworm feeding frequency

[Selkielass]

With worms, I find my snakes prefer several small feedings a week. Mice will hold adult snakes for about a week, but they still like a worm snack mid week if they can get it. (They do beg!)

I feed until they are full, or I see a visible bulge in their middles. If they are constantly piggy, watch out for signs of obesity and start limiting food. My snakes self regulate well on worms and fish, but will start to get fat on rodents if I let them.

If they are constantly piggy, watch out for signs of obesity and start limiting food.

What are the signs I can look for to determine this?

Do some searches here with the keyword 'Obese' 'Obesity' 'Fat' and similar.
Some threads will show scale spread on pregnant or merely fat snakes.
Fat garters start to look chunky not just in the middle, but in the neck, and sometimes sausage-y above the tail. (But be sure it isn't pregnancy, constipation or something similar.)
When Abby was getting fat, she became a lot more lethargic. She is much more active now that she has slimmed down a little. She is well grown, and I make sure she is actively hunting for a day or two before I feed her. If I overfeed her she just lays about and barely moves until her next (weekly) feeding.
