• Take a sheet of good quality white paper and wet one side by running it under the tap.
• Place the sheet on a flat surface, eg worktop with the wet surface uppermost.
• Sit your cat against the edge of the paper.
• Rub or brush the small of your pet's back so that scurf and flea droppings falls onto the wet paper or use a flea comb to brush your cat's coat and place the combings on the paper.
• Look for 'coal dust' which, after 30-60 seconds, goes reddish brown (this is the dried blood in the flea droppings).

Sometimes there are no obvious signs of fleas and your vet might suggest testing your pet's skin to see if it is allergic to flea spit.
