Hello,
What did the vet say with regards to the tail & the leg especially? Are they infected?
You do have them separated now, correct?
As suggested, continue using a diluted betadine solution daily on the affected areas, along with an antibiotic ointment to help ward off any infection.
I would closely watch that tail, for the discoloration traveling upward on that tail, as it will become a systemic infection & you could lose her to an infection. I would use a non toxic magic marker (water base) to mark the tail where it is discolored now. If it continues to travel upwards it will need to be amputated to help stop the infection.
Which antibiotic did the vet give you?
