Slime in urine?

I find the same thing, I never worried about it because I assumed it was just him shedding as its easier to shed when his skin is wet. I'm not sure though.

Mucus in the urine can be bad. Next time it happens collect the mucus onto a paper towel that is damp and stick it in a ziploc bag. Stick the sample in the fridge until you can get it to a vet for testing. Before 24 hours passes is best.If its a very small amount and white its usually not a bad thing, but if its pinkish or red you'll need to get your frog some meds.
