Cat and dog still scratching themselves even though they have been front-lined regularly

I found my latest rescue cats scratched a lot and I even found a few scabs around their necks. Frontline made no difference. I have never found a flea, but as a precaution I fumigated the whole house with specialst foggers, which protect from fleas for up to a year. The cats are no longer scratching and seem more contented. Like you I found that my other cats were unaffected.

Could it be a food related problem. Has the scratching got worse recently or has it always been a problem? Have you changed her diet. We took on a rescue dog recently and he was scratching frequently but it has got a bit better now that I've changed his diet to a different food. (more expensive - need I add!)

I think it might be food related too. My daughter was feeding her two small dogs cat's food and they were always itchy and scratching. When she fed them dog food the scratching stopped. Maybe what you are feeding them is the correct food, but they could be allergic to it.

A vet friend suggested a few drops of olive oil in the cats' food, in case it was dry skin causing them to scratch.

Thanks for all your suggestions. I have bought some different food today to see if that does the trick. Funnily enough, the little dog sometimes eats the cat food...not often...but that could be it. I will also try the olive oil tip from Shysal.

Most dogs have no allergy to lamb, for some reason, so I tend to always use a lamb and rice based feed.

Another thing that can affect dogs and cats is sarcoptic mange.Little mites that live under the skin and cause fiery itching. The vets now sell a stronger and more effective drops that cover far more infestations than front line and only cost about £4 more

When my cat had this problem the Vet said that carpet cleaner could be the reason - you know the sort you shake and then vac. Do not know if this still applies as it is now some time since we had our cat and I still miss her.

Maybe they are too hot , or could they be dehydrated ?

Sorry should have added - it was the powder - well the problem cleared up when I stopped using it....
