My friend had 2 and I had one that was part calico and part siamese. They’re very friendly and don’t mind if you pick them up. They do tend to meow a lot and make a lot of really funny different kinds of sounds. It’s like they have a totally different meow for every thing they want or with different emotions. Some of the meows can be very long and drawn out. If you’ve been around them for awhile you can kind of figure out which each type of meow means—I’m hungry, I need a rump scratch, I love your new wool blanket. etc.
They also like to be up high on top of things like your couch or your fridge or cabinets. They like to leap up there. And they tend to like to cuddle, usually up on the back of your chair next to your neck and will not hesitate to sleep at the top of your head in your bed.
I find them totally delightful, but if you find it hard to listen to a LOT of meowing, you might want to consider a more quiet breed.
