cats, LUTD and castration.

Question
Does my castrated cat has a higher risk of developing LUTD and possibly obtruction than a suxually intact cat?
He is 2,5 years old, he is not overweight, he likes dry food and he is allowed to hang out of home.

Answer
No. According to the many studies they have done, castration really had no effect on a cat getting FLUTD or obstructing. The only difference they found was that cats that were not neutered were less likely to survive the problem since they are less likely to receive veterinary care.

Male cats eating dry food are more likely to have the problem of obstruction due to the small size of the urethra. Wet food promotes more water in the diet and water is what keeps the urine dilute, which in turn harbors less bacteria. Less bacteria in the bladder means less crystal and stone formation.

So give your cat more wet food to encourage the water consumption. I was told that a water fountain encourages cats to drink more water also.
