They said neutralized tom cats are not so aggressive. But from my observation, some tom cats are just 'peace loving' even though they are not sterilized.
They are 'wise' as they have found out the secret of happiness - that living in harmony with other felines is better than fighting it out either for territory or tabby cats. It is not that they are weak, it is their peace loving nature. Even their facial features reflect a 'sea of calmness'.
On the other hand, those aggressive tom cats never look good. They either have fierce feature, started or haggard look. They normally have wounds and scars. Those which have been losing feline battles look real pathetic and seems to have lost all their cat confident. I have seen one over the hill tom cat with battle scars that was 'told off' by a youngest just coming out of its 'kittenhood'.
There is this large stray tom which would let another stray eat its food. Even when the other cat behave aggressively ....he just calming walk away. But the aggressor was not satisfied and continued its attack. Well, Mr Calm turned around utter a loud warning, rush forward ....Mr Aggressor fled for dear life. Mr Calm did not fight but he is imposing in his own way when pushed to his limit.
I have a tom cat (used to be a stray). He is 10 years old, consider a ripe old age for a feline. He has never been involved in a fight. He still looks pretty good compare to those aggressive stray toms which are much younger than him. You might say he is a pet, so it is not fair to compare him with a stray. But then our Mr Calm is a stray cat. In fact, Mr Calm is one of the most dignify and confident strays I ever come across. Nothing seems to ruffle his feather, I mean fur.
So if we want to be happy and look good, be peace loving and calm. Aggression does not resolve issue but likely create more problems. Just like what Gandhi said : An eye for an eye, only leads to the world of the blind.
