Steve the guinea pig got hay stuck in his gullet

He had to go to the vet and have an anaesthetic to have it removed. He's now on this super nutritious food to replace his electrolytes. We were told if he survives the night, he'll be ok. I won't tell you how much a Sunday emergency vet consultation, plus anaesthetic, plus removal of hay, plus sachet of powder plus vat is. But suffice to say, it cost 34 times what we paid for him. Steve, you're worth it!
