Antiseptics

Some how Charlie just got a scratch from being in the enclosure. That hasn't happened in the 7 months he's been using it. It's really tiny, but i was wondering what sort of antiseptic i can use on him. It isn't deep, only a tiny bit of clear fluid, doesn't seem to be any blood and a little of the fur is missing. I'd say it's only about 1/3cm across and down. The reason i ask is, it seems the betadine the vets gave us was thrown out, there was little left and i think it was getting old. I found that using something called tcp and savlon is not good for cats, but dettol is. I have an ear cleaning spray, and an antiseptic that both have benzalkonium chloride in them (i used the antiseptic as i dont know what other ingredients are in the spray) so i diluted it 1:20. I put it on the scratch with just a cotton bud so the smell wouldn't overwhelm him. he was purring his head off after i did it.

I would like to know what is the best thing for future references if we don't have the vet products.

Obviousely if he had a huge wound i'd run straight out and buy the betadine and call the vet.

Thanks.

run this by your vet but mine sent me to the drugstore for the cheapest neoporin ... the non pain one

He didn't cry when i put it on him, i think it must be a graze. Obvsiousely i'll keep an eye on it, but i'm not too worried at this point.

Thanks
