After losing a battle with my almost 3-year-old skinny pig (Hairless guinea pig) to dermatitis that went into the bones, I had decided to get a baby hairless guinea pig to keep my almost 2-year-old guy, company. I had taken the new baby guinea pig I named Phelix, to the vet. His penis had gotten stuck on the outside despite cleaning and lubrication, so I decided I needed some help with him. The vet had prescribed him meloxicam at .12 ml (the smallest dose I’ve ever had to give) for the swelling of his penis. I had given it to him just before going to bed, and when I woke up a bit early in the morning I noticed none of the veggie I left had been eaten. I lifted his house and he was already stiff cold, and quite frankly put, dead. I’m fairly sure he had a heart attack from the meloxicam, as I had actually given it to him the night after the vet visit, and not on the prescribed date of which he was totally 100% fine for. The vet has never in the history of me owning guinea pigs and giving them this medication, warn me about the heart attack risk. I guess this is a PSA of some kind to say meloxicam does have a chance of giving your guinea pig a heart attack. I only had Phelix for 4 days, so it was super devastating to find him passed. The breeder I got him from said I. could grab another one with no additional charge as it was such a fluke accident.
