Cat Deworming Schedule Guide

Why Deworming Matters

Intestinal parasites are common in cats, even indoor-only cats. Worms can cause malnutrition, anemia, and in severe cases, intestinal blockage. Some parasites (like roundworms and hookworms) can also be transmitted to humans.

Types of Cat Worms

• Roundworms — most common; transmitted through mother's milk or infected prey
• Tapeworms — segments look like rice grains near the tail; often from fleas
• Hookworms — cause anemia through blood loss; less common in cats than dogs
• Whipworms — rare in cats but possible
• Heartworms — transmitted by mosquitoes; prevention critical as treatment is risky

Symptoms of Worm Infection

• Visible worms or segments in stool or around anus
• Diarrhea or soft stools
• Weight loss despite normal appetite
• Pot-bellied appearance (especially in kittens)
• Dull, dry coat
• Vomiting (sometimes with visible worms)
• Scooting or excessive licking of anal area

Deworming Schedule

Kittens

• Every 2 weeks from age 2-8 weeks
• Monthly from 8 weeks to 6 months
• Then follow adult schedule

Adult Indoor Cats

• Every 3-6 months for routine prevention
• Annual fecal exam at veterinary checkup

Outdoor or Hunting Cats

• Monthly deworming recommended
• Quarterly fecal exams
• Flea prevention is essential (fleas carry tapeworm larvae)

Treatment Options

• Broad-spectrum tablets — Drontal, Milbemax (covers roundworms, tapeworms, hookworms)
• Topical treatments — Profender (applied to skin on back of neck)
• Prescription medications — required for some parasites like heartworm

Prevention Strategies

• Regular flea prevention (fleas are tapeworm intermediate hosts)
• Prevent hunting of rodents and birds
• Clean litter box daily (worm eggs take 2-3 weeks to become infective)
• Wash hands after handling cats and cleaning litter boxes
• Regular veterinary fecal exams
