Ooooh! Impacted anal sacs. Gotcha. That would be very a disturbing thing to hear. :)
fortunately it usually isn't serious, although it still sounds very disturbing. In the future, if you see him "scooting", it's a warning sign of that.
Thank you for both responses. Turns out my cat needed his sacks squeezed (?) and he had a few worms. I need to learn more about cats I guess. Seems this was no big deal.
Thanks again to both of you.

It sounds like a classic UTI. Hopefully your vet gave you a simple antibiotic course for treatment. :)
Hmm, I really don't know what that could be. It's good you are going to the vet tomorrow. The only thing I can think of is that it's maybe some waste of some sort but the vet will let you know for sure. Try not to worry too much about it.
