I just lifted out my 4 yr old guinea pig to clean out her cage and was quite alarmed to see what was a third eye peering back at me. Only it wasn't it was a wound ooozing black pus. How the hell could she have got in this state without me noticing?
I have squeezed all the pus out that I can, it smells like oh I don't know, bad enough to turn a nurses stomach. and is by the side of her mouth below her eye. I have washed her and it with water and salt water. her furr is glossy, her eyes are bright, I never had any reason to suspect anything was wrong, they have perhaps been squeeking more than usual but I thought it was because I had been lax with their hay...
I'm about to phone the vets obviously but does anyone else have any experience of this?
