We use it at work, never had an issue with it not working, but it's not super strong, hence why I suggested checking with the vet on best option, if he's infested he'll need something that will work quickly.

I agree talk to your vet about flea treatment. I used Frontline on my cats for a long time (probably about 10 years) and it was fine, then we had one summer when they got some kind of super-flea and the Frontline was just not cutting it so the vet switched us to Advocate and that is what I've used (with no further problems) for the last 5 years. Both of those are spot-on treatments. Bonus to Advocate is that it also treats worms so you don't have to do a separate thing, especially useful as my one cat is a terror about swallowing a tablet!

As for the house there are many sprays etc available but I would probably ask for a vet recommendation on that too as when we had those super fleas we tried no less than 3 various ones from Pets at Home, with no effect. When we went back to the vet and said it was a problem (cats getting re-infested with fleas because we couldn't clear the ones in the house) they sold us one. It stunk but it did the job. Unfortunately I can't remember it's name or I'd tell you.

I hope that you can get him all sorted out and settled happily into his new home.

Natarhi just as a heads up, I use Advocate, and you're right, it does treat against worms, except tapeworm, and you should get a tablet from the vet quarterly to give to your cat, mine is less than £5 between my two cats, so it's not expensive.

Thanks.

My vet has never mentioned that, which is strange as they're usually very thorough. I'll ask about it next time I go to get the Advocate.
