Love the 'mog - rat' name haha!
I have one devon rex varient, Migs, she is an absolute madam and 100% owns us. She is fussy yet moody, very intelligent and knows exactly what she wants. We put new lino down in the kitchen and the strips cut off the side turned out to be the best toy she had ever encountered. We put a piece of it on the coffee table (which she isn't allowed on and knows it) and she was doing a meerkat impression for ages looking at it... she eventually decided to try and get it whilst we weren't looking. She is a monkey and complete lapcat.
She is also a bit of a thief... known to steal things from handbags.. ie keyrings and things!
The Devon personality has been aptly described as a cross between a cat, a monkey, and "Dennis the Menace." Devons are highly active, playful and involved with everything. Powerful jumpers, very few spots large enough to hold them will not be explored and occupied. Devons have been found climbing brick fireplaces and perching on top of doors. Although little escapes a Devon's interest, Devons are very people-oriented. Most Devons invite themselves along for every activity -- preferably perched on a shoulder, lap, or wherever they can be closest to their people. They are accomplished food mooches, with "anything they aren't supposed to be into" only slightly less appealing than "anything you are eating." Many a bag of snack food left unattended for an eyeblink has suddenly sprouted two legs and a tail, with a Devon contentedly grazing inside.
Also a semi long haired black and white boy called Flea... I have no idea what he is. His previous owner told me his mum was half persian but I know most none cat people describe long haired cats as persian. He is super silky and so I don't know... he reminds me of a balinese we had!
