My one cat yesterday had flea treatment on him. It was the same brand. my cat was 8 months and 8 lbs. A couple minutes later, My cat started shaking so grabbed her and she was having a seisure. Then my daughter went in and washed the flea treatment off and he had another seisure. We didnt know what to do because our vet was closed. So I hurried up and looked on the computer and we rushed to the adamstown vet. After that we rushed back home because we have 2 other cats.They were fine but we washed off the flea treatment. So we rushed back to the vet and brought her down to this hospital down near exton. Right now guizmo ( thats our kittens name) is doing fine. But, this morning we found one of our other kittens dead under my bed.
