I sure hope that it's nothing serious and that he'll be okay. My Storm had the PU surgery because he became blocked 2 times. Yesterday morning I caught him peeing very small amounts of urine and he kept jumping in and out of the litterboxes. He was also acting normal so if I hadn't seen this I would have never known that anything was wrong with him. He also didn't seem to be in any pain.

I called my vet's office and they told me to bring him in right away and that even though he had the PU surgery, he could still be blocked due to scar tissue. Luckily he wasn't blocked but he most likely has a UTI and I'm still waiting to hear the results of his urinalysis and bloodwork. He's taking medicam for 3 days and bayrtil for 10 days. Please get your cat to the vet asap.
