Late last night I put food out for my 13 yr old cat but she didnt come which is wierd because for her so I called her and nothing but I just figured she was being stubborn. I went to lay in bed and when everything was settled I heard her cry and found her under my bed. I picked her up and put her by her food, but she was having heart palpations and had drool dripping out of the side of her mouth to where half her body was damp. She slowly walked back under my bed and stopped to pant heavily. I pulled her out again and sat with her in an open space and started to try and sooth her when i noticed her pupils were fully dilated and were unaffected by the light. Thats when she fell to her side and started grtting small convulsions. The rest of the night she kept having these convulsions 3 at a time about 5-10 minutes apart crying out every so often. It's morning now and she is still lying there, convulsions 10 minutes apart & pupils unresponsive. I'm worried and it's sunday, vet's closed.
