There is that front line stuff that you can get from the vets, but it's very expensive, about £15 a throw I think.
Been trying various sprays for the cats themselves. Zodiac is one, you can get it on the stall in the market. but you need to treat the house as well or it's a vicious circle.
Have  now discovered "Defest" an aerosol spray you can use on your carpets & such. The one I used last was about £6 and we needed 2 sprays, but once it's done the effects last up to 3 months. I believe they've now brought one out that lasts up to a year, which will obviously be more expensive, but more cost effective in the long run I should imagine.
You can get Defest from the Pet Warehouse in Ossie.
