Cat has sores on her head. Can I use polysporin? | Ask A Vet
Polysporin can be used on cats, as long as you wash the injured area first with antibacterial soap and warm water to remove any contaminants
A note about cat scratch fever…About 40% of cats carry Bartonella henselae, the bacteria that causes cat scratch fever, which can be transmitted to humans not only by cat scratch but by a cat or flea bite as well. Common symptoms include bumps or blisters and/or swollen glands around the wound and, as the name suggests, fever. Although antibiotics are sometimes used to treat cat scratch fever, it often goes away on its own, but why not do what you can to avoid it altogether by remembering to thoroughly wash even simple cat scratches and daub them with a basic antibiotic ointment, such as bacitracin or bacitracin/polymyxin (Polysporin).
My solution has been to use Polysporin Eye & Ear drops, which you can get for around $5, 10 dollars. It is a very "basic" solution and it won't hurt the cat's eyes, and I have heard vets say over the years that it is ok to use. If the eye doesn't respond, then it will need something stronger like antibiotics. In addition, this is what I used for cats and kittens that I have fostered whenever they had an infected eye. It was also used at the pet hotel where I formally worked.
