I think her behaviour is not recent as i used to hear them scrapping with each other when they were next door, it is not possible to seperate them, apart from those times they love each other, groom etc and sleep together,they were both spayed end of last year.

These kitties still belong to my neighbour, she just never bothers to come over and see them ever and leaves me to it, and they are more than happy and content here now, they have regular feeding, warmth, love and i make sure they are de-flead and de wormed, none of the above they were getting before, so no wonder they stay with me.

Duchess seems well enough, no signs of illness to my knowledge, i think this is just her,they have been together for about four years now.
