Will the operation compromise my cat’s capacity for self-defence?
No. This is an excellent question that provides the opportunity for a serious explanation based on vets’ opinions and scientific evidence. Your male cat will not become weaker or unable to defend himself. After the operation, his level of aggressiveness will decrease, which means that he will not feel the need to go and fight other cats as much as he did before. If attacked though, he will still be perfectly able to defend himself.
