How to Choose Over The Counter Cat Wormers

Selecting a cat wormer is about balancing safety, effectiveness, and practicality for your household. Always read the label and follow dosing guidance for your cat’s size and age.

Active Ingredients and Worm Types

Not all wormers treat every type of intestinal worm. Match the active ingredient to the parasites most likely affecting your cat.

Administration Method

Liquid wormers are often chosen for cats that resist pills. Consider your cat’s temperament and what will be least stressful for both of you.

Suitability for Kittens and Adults

Always verify the product is safe for your cat’s life stage. Kittens may need gentler formulas and different dosing.

Household Needs

If you have more than one pet, a larger bottle or a formula suitable for both cats and dogs can be more practical.

Dosing and Frequency

Improper dosing can reduce effectiveness. Use included syringes or droppers and stick to the recommended schedule.
