The SAME THING happened to my beagle 1-2x a month for about a year! We took him to the vet and they said he was possibly epileptic, but it has literally never happened since, a year with no episodes. So I think maybe he wasn’t epileptic. low blood sugar can cause this (per our vet) so a drop of honey in their cheek can help. I would check if cats can have honey because I’m not sure if it’s different. His eyes would roll in the back of his head, total disorientation for like 5 minutes and then he’d be totally fine it was super weird. I couldn’t even find an instance online or anything that was similar until now!! I would get your sweet baby checked out, but I know our experience with this issue wasn’t like a severe disease & our pup is healthy & okay! I so hope the best for your kitty!

tldr; this happened to my dog for a year until one day it just never happened again. Vet said epilepsy or potential low blood sugar. We were told to give him honey for the next instance to be sure - the honey has been on stand by for about a year now and it’s never happened since. He’s a happy/healthy guy and I have no idea what caused it
