Calicoon is having seizures about once a month (23 year old female Maine Coon)

Hi, My cat is elderly and having seizures about every three weeks.  It started last November and she would walk around in a circle then collapse and start shaking.  I hold her and she seems to stabilize and them come out of it.  Yesterday, it appears to be a 'grand' seizure and she shook for a good two minutes and a lot of saliva came out.  When I touch the top of her head, she stops for a second and then starts shaking again.  She then recovers, walks around dazed and what looks like - remapping the environment and then appears to be her normal self.  After November she started eating almost twice as much, but is slowing down a bit now.  Any advice, like stories, cat poetry would be appreciated.  Thanks much.  Sorry, photo kind of blurry.

They do eat ravenous afterwards *I was told so passing on *  you need to monitor write down the episodes how frequent they are 

time start and finish. Normally few seconds to a minute long anything longer take her to the Vet.  This is during treatment already

if you have not seen a Vet you really must get blood work done Vets can diagnose hopefully treat where it stems from...She needs meds to 

control Grand mal seizures they do the most damage   for the little ones keeping her wide awake alert totally conscious, did hear

using a bag of Frozen peas on their back helps to snap them out of it before it progresses....have used a pressure point under the nose

works well but again only if you're home.  New method is using CBD oil purchased at medicinal shops it's a pet product some oils are stronger than  

others, so it's a matter of research. I believe it helps prevent inflammation. 

Beautiful kitty!
