Hi, just wanted to post a quick response x I have studied a degree in animal management, volunteered at an animal sanctuary for 4 yrs and also a year work exp. at a vets. Please do not bathe your cats paw in plain tap water, as this can introduce infection, use cooled boiled water with a little salt to bathe if needed, don't allow the cat to lick the paw.
Just continue to tempt with yummy foods, and keep an eye on her really, with an abscess she will feel yuck and be unlike herself, so please do not be too concerned, though any major change in behaviour should be reported to your vet.
Also, cats purring does not always indicate happiness so do not worry if she isn't purring, many cats pure for comfort, or are in pain or anxious, not just to exhibit pleasure so don't worry about this too much either x
I have 4 cats and one or other is always doing something to make me get my bet books out to double check stuff x bless them :)
