Hard yellow sap like substance in tank

I got home from work today and my adult female checkered garters tank was covers in this hard yellow “vomit”?idk what it is. She ate last weekend and is due for a feeding on Saturday. She’s very alert and seems to have an appetite. I feed her two fuzzy mice a week but last weekend she only ate one. Hot side of tank is mid 90s and cool side is room temp, usually 73to75 degrees. I don’t have an AC unit. But it’s been really hot the past few Attachment 15173 ays and the cool side of the tank may have gone up to the mid 80s. Could this be the cause??

Slugs, jellies, unfertilized eggs.

It that a normal? She hasn’t been bred for two years and has had no contact with males since then

Yes...unfertilized eggs are normal when they dont breed
