What´s the usual weight for a 10 months old male Maine Coon kitten ?

Answer 1

Depends on how big they're going to get. If he looks about the size of a regular cat and your can feel his ribs when you give him a firm pet, then he's okay.

I've had Coons that weighed as little as twelve pounds to my current one who weighs close to eighteen.

Answer 2

maine coones can get very big, so if the cat seems a little heavy, I wouldn't worry.
