I agree with Mommoffuzzyfaces - it's down to personality. All the cats we've ever had have been totally different.
Bagel and Ketchum are brother and sister and are chalk and cheese.
Bagels so sweet,loving and friendly. She is always 'talking' and 'chatting' about her day. She doesn't like sitting on laps though.
But Ketchum is really shy - hates folk visiting and can be scared by his own shadow. Whenever he's frightened he can be found under our bed! But he will come and sit on my lap at night time for as long as I let him - just so long as I don't try and cuddle him.
