Preventive care


When a kitten and puppy is still with the mother, he / she receives antibodies against pathogens through the mother’s milk. That is why it is important for the health of puppies and kittens to stay with the mother until at least 8 weeks of age. This is because the body itself does not make enough antibodies against pathogens before then.

In addition, puppies should be vaccinated at 6, 9 and 12 weeks and kittens at 9 and 12 weeks to produce their own antibodies against fatal infections.

For optimal protection, after the last vaccination it is wise not to bring your puppy or kitten into contact with peers who (possibly) have not been vaccinated.

To ensure the protective effect of the vaccination, your dog or cat must be vaccinated annually.


Worm infections weaken young, sick and old animals. If you have just taken an animal home, always deworm it on the day of return and two weeks later. Then follow the deworming schedule: every 2 weeks until the age of 12 weeks, then once a month until the age of six months and then at least four times a year against roundworms and tapeworms. If your dog or cat has fleas, it is advisable to deworm together with the flea debris. If your dog or cat eats a lot of prey and faeces, it is advisable to deworm monthly. Always use a wormer with the active substances Milbemycin oxime and Praziquantel.


When combing: Flea excrement looks like brown granules and is around the neck and at the base of the tail. When you wet these granules on a tissue, it will slowly discolor to blood.

If your pet has fleas, put all baskets and toys in the washing machine and treat all animals in the household for 3 months.

Always use only products exclusively for cats in cats: Dog anti-flea products contain a substance that is toxic to cats.


With a microchip under the skin, your animal can return to you on the basis of your registered data if it is missing and found. A chip is not a GPS system with which you can track your pet, but the experience is that most missing animals are reunited with their owners by their microchip. Chipping is recommended for all animals: Also for indoor cats: they often cannot find their way back if they escape or fall from the balcony.


If you have just got a new animal at home, it is best to give the animal the food that he / she is used to. Sudden changes in food coupled with the stress of moving can cause an upset stomach and diarrhea.

If you want to switch foods, it is best to do this gradually by mixing new and old foods. You can request free nutritional advice from Paraveterinary veterinary assistant Merel Verheij. By choosing a diet that suits your animal and nutritional status, many ailments can be prevented.
