I have 2 cats, (too). A 13 year old rag doll, and a 3 year old Maine coon. These are both extra gentle and laid back creatures. The rags are genetically compelled to follow you around the house, while the coonies like to "hang out", while napping next to you, with one eye open.
I've had two of the Maine coons so far. I lost the last one to kidney failure, (common in cats), but this was brought on by diabetes and obesity. (Bangor weighed in at as much as 24 pounds). And yes, I did have to inject him with insulin twice a day for almost 2 years.
The new guy, "Baxter"(*), is hovering about 16 pounds or so. I call him "the runt of the litter", as Maine coon males can run as much as 20 to 24 pounds, without being overweight. No matter though, everybody who sees him says, "Jezus Krist that's a huge cat". If I live long enough for a 3rd coon, I may name him "Jezus Krist of Portland", (Maine, of course). "How'd you guess his name", I'd reply, deadpan. (Duh)!
(*) Funny story about his name. Before I got him, he had 2 owners, I'm guessing both female. His 1st name was, "Le Mew", the 2nd, "Fabrege" (yes, that's spelled wrong). I had entirely enough of walking into the vets office with him under that name. so I named him "Baxter". First, it's the name of a state park in Maine, and second, I thought it sounded like the name of a vice principal in school, you might be sent to when you were bad, "Mr. Baxter".
