All three of our cats went to the vet last weekend for regular check-ups. All three of them are doing great. Tigger has a mild heart murmur which the vets are keeping a close watch on, but his condition seems to remain stable. Belle weighed in at 19 lbs, but the vet is not concerned with her weight since she is naturally a big cat. (Actually, all of our cats appear to be above average in natural size!) Tigger weighs 15 lbs and Gizmo - our tallest and fluffiest - is just under 13 lbs.
