Okay! Thank you so much.

He was being fed once a week because he was extremely underweight when obtained, and I had worked up to feeding him more often (the people he was from fed him a mouse once a month and he was a teeny little thing, no more than two years old, and had done that since he was a baby...) and was trying to gain some of that weight back. I will definitely change his feeding schedule to be better, though, thank you so much for alerting me.

Should I do this gradually, like how I built up to feeding him rats on a weekly basis? Or should I immediately switch?
