In the last week my cat either had a seizure or a stroke. She stops eating and holds her front paw up. She starts shaking and her legs give out. I hold her close to keep her safe and she doesn't stop purring as long as I keep petting her. Her eyes have rolled back and her fur flattens to her face. She lays on me and tries to get up, which she cant. A fe minutes later she jumps off me like nothing even happened. She goes back to eating and sleeps on her chair. We have recently moved and this has happened when I take her back to her old place to visit. (My moms house) Im not sure if this happens when Im not around. Please help me.:confused:

This sounds very serious. You need to get her to a vet ASAP. This doesn't at all sound like a reaction to stress. She may be experiencing "mini"-strokes, or it may be neurologic. Bear in mind that purring isn't always a pleasure response: Cats sometimes purr when they are in pain. Please, please, get her checked out.

Is there anything at your new place she could have gotten into? Lead paint, pesticides, etc. The vet is sure to ask this.

Yes, take the kitty to the vet! Poor thing.
