Female Siamese question
I have two Siamese cats a female 3 years and a male two years. I live in a second floor flat with private balcony. Both my cats are indoor cats. Every time I open the front door to go out or come home my female runs out on the balcony and starts rolling around on her back and rubbing her head and face on the ground. She never does this on the private balcony and has now started to try an go onto the stairs to do it. The male sits and watches but never bothers to go out and join her.
Can anyone tell me why she does this. At first I thought she liked the feel of the cold ground on her face but see never does it on her private balcony now she tries to wonder off when the door opens. Both cats have been desexed.
She doesn't run off just roll around rubbing her face.
