A little update, had all three to the vets yesterday, Gizmo and Pixie are fine and healthy so no worries.
When the vet saw Spike she asked what age he was. I explained the shop claimed six weeks and she doubted it as well. At a guess she reckoned four. She was more concerned that if he was six weeks old then she suspected a couple of things, possible mange due to bad skin and weight loss or that he wasn't just the runt of a litter but was the result of a little too much "inbreeding" and would forever have health problems such as breathing issues etc.....
At this point she tried to pick Spike up and he decided he would show her just how fit and fast he was by sprinting around the box 98), as soon as she caught him he decided he would show he didn't have breathing problems by producing a supersonic squeak that could almost break glass :o. The vet was highly impressed with his lung capacity and asked a couple more questions.
How many guinea pigs were housed with him? Was he scratching a lot and how was he eating?
I told her there were five other pigs with him and he seemed to be getting bullied. This seemed to satisfy her and she thought since he wasn't scratching and was eating like a little muncher that his skin condition was also as a result of the bullying........
He got his skin treatment and has to go back in a week for the second application, but last night he was as perky as usual and has decided he now loves green beans, so hopefully he'll put weight on and get his fur nice and shiny and healty..... :smitten:
