Male Cat Fixed, not urinating after surgery?

Hi,

Just got the vet to "fix" my 9-month old male cat late Tuesday morning.
he came home this morning (Wednesday) and so far hasn't urinated much or at all; is that normal so soon after such a procedure? He has squatted in his pan a couple of times, but nothing comes out yet. When he squats he is in the pan and in the squatting position for a longer than normal amount of time.
I will certainly monitor this, but was wondering if this occurs so soon after getting a cat fixed.

Thanks,
Dale

Call the vet

Call and ask how much fluids he's had. Mine didn't urinate till the evening after I brought him home (he went home at 10 am). The first time it was just a tiny bit. In his case, he simply needed to drink and eat some wet food.

Having had fluids withheld from me before surgery, I can honestly say after a few hours there's nothing left to pee.
