DH noticed she was moving oddly, one of her back legs - it looks like she is limping. He turned her over and there is a small hole underneath, on her abdomen and out of it is a long stringy substance/thing, quite thick, sort of if you squeeze toothpaste out of a tube, that size and consistency, but with three bulbous bits at the end. The hole is quite small, and looks clean.
Shes not herself, hiding behind the plant pot.
What do you think it could be? Infection, tumour, hernia? Will get her in vets in morning.
