Terambulan, is quite correct, you use tweezers to remove it if it is a tick. You can easily tell if it is a tick. When ticks first attach themselves to either cat or dog, they are a creamy white colour and look oval, fat, and soft. If they have been attached for a couple of days, then they look black because they are gorged with the blood they are sucking from the animal. As Terambulan says, you must sterilise the tweezers, this can be done as he says with a flame, or by dipping the tweezers into alcohol (vodka or whisky). or boiling water. However, the tick's mouth is like little claws with which it bites and holds on to the animal. Before you can remove the tick, it is necessary to make it release the claws, which can be done, by either carefully touching it with the lit end of a cigarette (with the ash knocked off), or putting a couple of spots of alcohol on it. Then quickly remove tick with the tweezers, and destroy it as Terambulan suggested. I know they look horrible, and the first time is the worst, but be brave and do it. Last instruction, pour yourself a large whisky. As Woofgang says, frontline prevents ticks, but this needs to be kept up-to-date, especially if the animals go anywhere near land where sheep have been, as these ticks are commonly called 'sheep ticks'.
