My Cat is Positive for Giardia

Giardia in Cats

Giardia is a microscopic parasite that can cause diarrhea and tummy upset in cats (and sometimes people). Treatment works best when you keep things clean and dry at home — this helps stop your cat from getting reinfected.

Cleaning Routine During Treatment (First 7 Days)

Litter Boxes

  • Scoop waste at least twice a day.
  • Dump all litter daily.
  • Wash the box with hot, soapy water, then rinse with a mild bleach solution (½ cup bleach per gallon of water).
  • Let dry completely before refilling with fresh litter.
  • Each cat should have their own litter box if possible.

Bedding, Blankets, and Rugs

  • Wash every 2–3 days in hot water and dry on high heat.
  • If it can’t go in the washer, scrub with hot, soapy water and disinfectant, then let it dry completely.

Hard Floors and Surfaces

  • Mop or wipe down daily with hot water and disinfectant.

Your Cat’s Rear End

  • Wipe or bathe your cat’s backside once a day during treatment to remove cysts from the fur.

Hands

  • Always wash your hands after cleaning the litter box or handling your cat. Giardia can spread to people.

After Treatment (Next 7 Days)

  • Continue cleaning every 2–3 days.
  • Do one final deep clean of litter boxes, bedding, and floors at the end of the week.
  • Keep scooping litter daily.

How Long to Clean

Plan for 2 full weeks of regular cleaning — 7 days during treatment and another 7 days after. This breaks the cycle of reinfection and helps your cat stay healthy.

Prevention Tips

  • Give each cat their own box and bowls.
  • Keep litter areas dry — Giardia thrives in moisture.
  • Wash hands after cleaning or handling stool.
  • Have all cats tested and treated if any test is positive.
