Males VS Females???
Males neutered before 6 months old do not spray. The Genetic lines and personality traits of the parents play a huge part in how the kittens personality will turn out. That being said; I always consider Health first with picking new cats for my breeding program and personality 2nd. However if both of those are not excellent then that cat does not make it into my program. The simplified answer is: Males and females are both big love bugs the males slightly more consistently so with the females having their little PMS moments. **There are only two colors in cats that are linked to personalities. Tortie/Calicos and Red's. Reds no matter female or male (although red females are very rare) are always going to take the term Love-bug to the next level. I don't know why this is but it is true. I have heard this from every breeder with a Red Stud or Queen. Torties/Calico's are always going to have "Tude" and be very Diva like.
news flash: allergens males vs females
It is not a Males VS Female equation. Some breeder put it out there on Wikipedia that Females were lower in fel d 1 levels than males. Great marketing tool for a breeder that always has more female kittens than males. News Flash Anyone can edit Wikipedia. The Protein OR fel d 1 levels are unique to each cat. It has to do more with the lineage of the cat not the sex of the cat.
sizes Males VS Females
Average weight of adult Siberian male (13.2lb-22lb), average weight of adult Siberian female (8.8lb-13.2lb). Spayed and neutered pets will always be bigger than my intact breeding cats as the Spaying and Neutering causes cats to bulk up.
