Not Well

Poor Pippysue hasn't been feeling well, so we took her to see Marnie the vet. I was fearing the worst, and had convinced myself her kidneys had packed up. 
Thankfully, Marnie thinks it's just an infection - known as an Infection of Unknown Origin - where they don't know where it is or how she got it. Apparently it's quite common.
She's back home now, with a heap of anti-biotics. 
Hopefully that will do the trick.
If it doesn't, blood tests will be in order.
