I sort of prefer the idea of a spray than concentrated in one spot.
What do people recommend and why, and which brands?

Thanks.

The sprays are more dangerous to humans which is why when Frontline spot on was changed from POM-V to OTC the spray remained restricted. Not only would you be breathing in carcinogenic droplets but so would your cats. Nothing is completely safe and there are times when I believe it is important to consider the bigger picture. I particularly wouldn't even consider a spray if there are babies or small children in the household.

I use drops - Advocate

I use the Frontline Spot-on. I've tried advocate in the past too. It did it's job very well, but unfortunately it also seemed to sap all of rumbles energy and put him off his food for a few days... I've seen no such side effects with the frontline.

Think I'll go with the frontline then. Thanks for the help.

There are a couple of types of frontline - Frontline and Frontline combo. The Combo is only available from vets. I found this type caused localised hairloss at the site where it went on the neck, so went back to 'normal' Frontline.
