Cat seizures

My cat had a seizure saturday mornin, i took him to the vet, he sed he may have eathen something, i went home noticed some meat and bones ware missing that i throw away in the garbage. Doctor sed to waith out some days so he can digest it. He done his 'things', acts normal. Didnt have any seizures for 3 days but he did have saliva drooling once every 4 h. Then after 3 days he had another seizure. I called my doctor told him he is geting worst, and he told me he has no clue. I took him to a new vet that day, he took some blood tests. This morning we got the results. aparantly his blood test say he is ok, yet now he has seizures 4 times / day. My doctor told me to go home and waith for some weeks lets see if he's gonna live. I called another vet he gave me epilepsy pills and pills for his liver, but he sed he doesnt think ill work. Ive visited 4 vets till now no one could help me, and it past a week since he started them
