Two of our cats like an occasional treat of garlic sausage, just a couple of small pieces. But also they have frontline every 5 weeks. If you are worried about the expense you can buy it on online more cheaply than from the vets. I have a 3 yr old tom cat who has epilepsy, and his tablets cost �14 every four weeks, and that's for the rest of his life. Unfortunately the tablets are prescription only, so unable to take advantage of buying online. It would be worth a look to compare the prices.
