New litter or a new rescue?
Start here.
Puppies, kittens and new arrivals often pick up worms, Giardia or Coccidia from their mother or their last home. Zap-Wormer can be used from 2 weeks of age, and CARE comes in 500 ml and 1000 ml bottles for a whole litter.
“I also religiously use their combo coccidia and Giardia treatment with the dewormer for every cat and kitten that we intake.”
What it looks like
- Pot bellyA round, swollen belly.
- Loose stoolSoft or watery, sometimes with mucus.
- Not gaining weightEating well but not growing as expected.
- Worms in the stoolStrands that look like spaghetti.
- Dull coatLess shine than littermates.
Why it happens
- From the motherSome worms pass to puppies and kittens before birth or through milk.
- Shelters and kennelsMany animals in one space spread parasites easily.
- The stress of a new homeMoving and weaning make young pets more likely to show symptoms.
- Shared yards and beddingEggs and cysts survive in the environment.

Good questions
From what age can I start?
Zap-Wormer can be used from 2 weeks of age. The CARE label says it is not for pets under 2 weeks old.
How much CARE do I need for a litter?
Add up the litter's weight: each pet needs 1 ml for every 5 lb, once a day for 7 to 10 days. The 500 ml bottle costs about 16% less per ml than the 120 ml, and the 1000 ml about 20% less.
Can I treat the mother?
The CARE label says it is not for pregnant or nursing pets. Ask your vet what is right for the mother.
How often should I repeat Zap-Wormer?
The label suggests repeating every 3 to 4 months.
