Persian kittens & cats in Bracebridge, Ontario

Marshmallow is a sweet, 4 year old girl but only likes attention on her own terms. She will not hesitate to curl up at your feet but doesn't like to be picked up. She is very skiddish and afraid of dogs, other cats, small children, strangers and loud noises. She would be best suited in a quiet environment with only 1 or 2 people without young children and pets. She does not bite but any other environment would scare her. She has been raised with an older cat and dog but anything new pets would terrify her. She does like to play with a laser light and finds peace in her kitty tent. Full disclosure - She is litter trained but does pee on beds, couches and mats or clothing on the floor. I've tried every option to prevent her from doing this but nothing has worked. I'm not sure if it is because of the other pets in the house. Vet check came back clear of any medical conditions regarding this issue. She needs a quiet and safe space and lots of grooming attention.
