From my understanding, a kitten should be neutered around 6 months mark. My Oliver is 4 months old, however he is quite robust and has grown exceptionally well, he already looks like a small (and pudgy) adult cat. (Well, physically I mean, he still acts every bit like a kitten of course...) Will it be adviced to get him neutered as soon as possible, or should I wait for another month or two? I know a few people who have waited too long and their cat started marking all over the house, which was not exactly something for them to celebrate over, and I would like to avoid that situation... Any advice would be appreciated!!
