Can you use a regular hydro..

I've already applied a frontline flea treatment but her skin is so dry and scabby and irritated. Looking for effective low cost way to treat her and make her feel better.

They DO make hydrocortizone creams specially for cats, and dogs, too. But if you're looking for a cheaper remedy, try vaseline. This will also keep the fleas from irritating existing sores, and it won't hurt the cat's system if they lick at it. Jusy try and not apply too much.

I don't know. Contact your vet and ask.... to be on the safe side.

The best thing for fleas is Advantage. I used to work for a vet and he said that the more things a product protects against, the less powerful against each thing it is. So if you don't have ticks or anything else, stick with Advantage. Then you won't have any fleas and the rest will fix itself. Also, they do have itch medication for cats, but I'm not sure of how much it is.

She will just lick it off. Leave it alone.
