Maine Coon cats are wonderful. My mom had a beautiful female, who didn’t come *near* that weight. She was large but not that large!
Maine Coons have the habit of sniffing out every single item brought into a house. If they take a fancy to it...they remove it from view (like your keychain attached to a rabbit’s foot or a sunglass container). Once they stand on the balcony, you can observe them making the rounds and sniffing in all directions.
This would also be the last cat on Earth that you’d want to drag the cat travel container out for a trip to the vet. This breed can tear you up with the claws...which they normally never show you for 99-percent of the time (being overly friendly). Once that cat container is brought out...the claws come out in anticipation of the trip.
