I took my guinea pig to the vet last night as he is dragging his hind legs. He is 6 or 7 years old. The vet said he needed an X-ray and if nothing can be found a scan. The x-ray alone is £400 and a scan £600 plus consultation and any pharmaceuticals he may need. So a minimum fee of £1k. My guinea pig isn't in any pain, is still lively and eating very well. I read some other similar postings and have decided to try Osteocare 1ml twice a day. I guess the point of my post is to ask if I am doing the right thing?
