I have a 7 year old male cat that as of 5 days ago started vomiting clear or greenish liquid and stopped eating, drinking and washing himself. He had a full blood panel that was negative for everything including poison. The vet x-rayed his tummy and though it could be a bowl obstruction so she gave him an enema. He had a BM and nothing looked abnormal. The vet also gave him a shot of anti-inflammatory and antibiotic. I have been force feeding him every 2 hours but there is no change in his condition. We live in the mountains where there is lots of wildlife including raccoons. I don’t know if this is a virus, spider bite etc. Any help or advice you can give would be very helpful.
