Why should I neuter my male cat?

Male cat neutering prevents cancer of the testes, prostate issues, transmission of FIV and FeLV. These diseases are sexually transmitted or fighting with infected cats, and neutered males become much less territorial. This also prevents wandering around (risk of car accidents) as well as urination “marking” in the house (but only if it’s done early!). Last but not least, neutering reduces the strong smell off coat.
