Hi i've had different tales from people - i just got a new male cat and was trying (still am) to introduce him to my female and male cat. Some told me i'd have trouble having two toms as they'd fight, others said it would be the female who didn't like him. It turns out that neither are too keen on him. I'd agree with Ela i think its the temprament, i'd consider getting one maybe a little younger than as they'd both be kittens so could play together.
