What reason are you wanting to use it for?
How much does your cat weigh?
Where did you get the medication, and what is the strength of it?
Yes, that medication is ok for wounds regarding cats. It is a very broad spectrum antibiotic that can treat many things from urinary infections, respiratory infections, and wounds that are open to bacteria.
It is dosed by 5mg per pound of body weight.
If you can handle the cat, start flushing the wounds out a couple times a day as well with plain saline to keep it clean.
