Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
Ear mites would not be able to penetrate into the brain and cause seizures.
Ear mites are oxygen-breathing creatures, and could not live submerged in fluid or in solid tissues.
Unfortunately, seizures in an elderly cat may be caused by a brain tumor, as the most likely explanation.
Dear Dr. Drew,
I'll be waiting for your reply :)
I'm going to observe Jerri for the next 24 hours to see if the same sort of "episode," happens with Jerri. I thank you so much for this wonderful service you provide! It truly is wonderful and I'm fortunate to be able to find such a service that exists! It means more than you know!
With most sincere thanks,
I am so glad I could be helpful to you this evening!
