We are back from the vet. She drained the fluid again and gave him some Valium since last time he was a little feisty. So now I have a drunk kitty, LOL.
We discussed our options, and to stop the cysts from filling up surgery would be the only thing to do. I asked if that was ok with his age and she said 13 isn't too old.
And I forgot to ask what kind of cysts they were. I'm exhausted. I've been up since 3:30 with Zoee and her having another seizure. She is currently at the ER vet as I type.

So for now I'm going to discuss this with Bruce (which should be pointless) and go from there. I'm just very nervous about him going under for surgery at his age. I think I'll talk this over with my sister too, see what she thinks (she's a vet tech).

Thanks again, everyone.
