Additional problem to a cat's health are worms. Worms are a recurring problem for most cats. It is not always easy to spot the symptoms. However, if your cat seem unable to gain weight, take him to the vet for worm testing. You could also check his stolls for something that is small and white in color which looks like grains of rice.
Roundworms, tapeworms, and hookworms are the most common. Your vet will tell you that it's best to use a reliable worming treatment every three months to prevent any serious worm infection. The important thing with worms is to break the cycle, which may take more than one treatment.
Worms are a health risk and can be fatal, but properly treated can be cured effectively. Same goes to the owner :)
