Cheddar is being quite aggressive to Penelope . She chases her around, not sure if that's play or not. But then she growls at and goes for her, she will sometimes back her into a corner.
Penelope doesn't seem hugely bothered by it, and is often lying on her side with her tummy exposed. I've put the pet remedy back on, and ordered some feliway friends. They will happily sleep close to each other on my bed. I'm a bit worried as they are going to the cattery in a few weeks and will share a large pen.
