Dronspot is a spot on worming treatment for cats. Intestinal worms can easily be picked up by your cat from eating microscopic worm eggs from the environment, from hunting or from swallowing infected fleas when grooming. Kittens can even pick roundworms up from their mum when they suckle her milk. Dronspot takes the stress out of the worming routine. It’s a simple treatment that is applied at least once every three months to keep worms at bay.
