Symptoms include nausea and vomiting, the cat wobbling, acting uncoordinated, appearing drunk, twitching muscles, head tremors. and depression. The symptoms shown depend on how much is ingested. Only a vet can determine by examination of a cat whether treatment or not will work for a cat who has ingested antifreeze. If Oliver has ingested antifreeze, this is a medical emergency and he needs to see a vet now. Best of luck.
