Found out what's wrong with Belladonna's feet. Binx has it too. "Bumblefoot." Doesn't look good. Apart from antibiotics, Bella may need surgery and mum says we don't have the finances to take her to the vets for that.
I know quite a bit about what is involved in this surgery, and it seems very simple. I have done similar things before, and I have actually treated her infection already by soaking and pulling off the scab and clearing out much of the hard, rubbery puss. All I need to do is make an incision and clear out the gunk inside, then wrap it up and continue antibiotics. "Surgery" makes it sound daunting though. Farmers treat their stock all the time, right?
