I share that sentiment with a post about my cat, but I'm sure, as a cat lover himself, he won't mind.
So I think little Tegan is having seizures.
I came home from work a few weeks ago (09/11/2012?) and found her scrabbling manically on the wooden floor by my bed. I picked her up and comforted her until she calmed down as her breaths were rapid and she was panting. She'd also wet herself resulting in me having to wash my duvet. :/ Back then I wondered if it had been a fit or if I had somehow startled her and launched her into a full panic attack. She's very nervous, so that wasn't a stretch. As she seemed okay after that, I resolved to wait and see.
But she had another attack on Friday morning. I was woken way too early by her scrabbling on the floor again, this time in my hallway. Same thing happened. More panting and shuddering and she ended up splayed out in her own pee as if her back end had just given up. I propped her up and her legs seemed fine, so I washed her up and she seemed okay after that, demanding food. But as this was a repeat I took her to the vets asap.
They didn't have a clue, so as she is otherwise fine and not poorly we are treating her for a possible ear infection - working on the hypothesis that because she already has neurological problems that affect her balance and gait, that she might have lost her balance while scratching her ear (which she does a lot) and triggered a panic attack. It's a much cheaper route than doing an MRI scan for epilepsy, but somehow, given her history and the nature of the attacks, I think epilepsy or something is more likely.
Looks like I'll bathing her in the middle of the night again in the future. :(
On a cheerier note, here's a nice pic of her:
