Cat's are good at concentrating their urine and holding it for long periods of time. The only time I would get concerned about them not being able to urinate is in cases of an obstruction, or acute renal failure. In both cases there would be other signs.

In renal failure they would act sick - less active, not eating, vomiting. In cases of obstruction the cat would be restless and seen straining to urinate throughout the day.

If Theo is otherwise acting normal, then I wouldn't be worried. If he does show any of the signs above, then it would be an emergency and I'd reccomend taking him to the vet as soon as possible.

I hope that helps and all is well with Theo.
