I noticed 2 small insects moving on the paper towels. They were beige/yellow and about 1/16 long.
There are over 300,000 species of beetle, 100,000 species of butterfly, 100,000 species of fly, 100,000 species of ants and wasps, etc. for a total easily exceeding 1,000,000 species of insect.
Trying to ID the insect based on it being yellow and 1/16 of an inch isn't going to be easy! Of course, then there are mites, ticks, etc which aren't even insects.
Look at some books and see if you can narrow down what type of "insect" it might have been so we might be able to help.
I can say that snake mites are much smaller than that and are black. Ticks come in a variety of colors, but you don't often find them loose in the cage.
