How much does your Maine Coon weigh? The biggest one I know weighs 22 lbs. I thought they got bigger.
My vet in California had a 28-pound Maine Coon. Tragically, he killed the cat by accident. It could not tolerate the anesthetic he used for its surgery.
The poor man was devastated for a long time.
The last time Bubba was at the vet, he weighed around 15 lbs. I would not be surprised if he weighs over 16 now.
