Flea collar and natural tick are suitable for small cats over the age of 3 months. The flea collar and tick fully provides effective protection from ticks, fleas and mites. The guidelines should be comfortably proportional to the fleas around the cat's neck in order to touch the skin and ensure that your cat cannot remove it. In general, you should be able to put two fingers under the collar. Any additional length should be cut and disposed of. The collar of fleas and tick cats should be replaced almost every 8 weeks, in case of frequently strong injury.
