Our 4 year old cat yesterday was pacing about, wouldn't settle (normally a lazy lump who loves to curl up on the bed/sofa), and took a swipe at both my DD and me. She can be a bit scratchy at times, but I'm pretty clued up to when she doesn't want to be touched, so yesterday was out of character.
She then started prowling about the house doing that low growling thing they do and hissed at me..she's never done that before. It was like there was another cat in the house or something (we only have Rosie).
She's up now, but unlike usual she only ate a tiny bit of breakfast and has curled up on our bed and just looks really miserable 
She has a scratch on her nose..there is a cat that seems to be intent on coming into our garden and bullying her, but I can't see any other injuries.
Any idea's? Don't want to bundle her into her cat basket unnecessarily and take her to the vet as she hates it so much. Should I just watch and see?
She just looks sad
