We had a cat named Dewey. he isn't the nicest cat. One night we were woken up to see something terrifying.Our cat Dewey on the ground,can't walk,eyes going back and fourth (Like his eyes were following something.)he would turn his head all around,he was meowing,he couldn't walk,he had diarrhea.,it was all bad. I should mention before all of this happened,he was becoming a surprisingly sweet cat,and he is pretty mean. Now,we had put some flea spray on our dogs,just meant for dogs.Well,after the dogs got "Pretty" dry,we let them in the house. This too was before all of this trauma.So once this occurred,we checked and look at the bottle realizing it said "DO NOT USE ON CATS" which we didn't. It has to types of chemicals,one natural one that won't harm cats,then one called Patherin (I think) that poisons them.I found this site that showed signs of this "chemical" poisoning,and it says walking drunk,gastrointestinal problems (He had diarrhea),and seizures which we were not sure what all the screaming meowing,eyes,and neurological crap was,it defiantly effected the cats brain. Anyone ever had this happen? Any ideas? It also said death,he may be in the woods dead. Please help.
