How to Tell If Your Cat Has Parasites
📝 Summary
External parasites show as itching, hair loss, lice, white flea eggs, and black 'flea dirt' that turns red in water (also implying tapeworm). Internal ones show dull coat, pale gums, tarry stool, vomiting, appetite loss, swollen belly, lethargy, or visible worms. See a vet for testing.
1 External Parasite Signs
The main sign is itching—frequent scratching or biting means fleas or similar; act fast. Skin damage, red bumps, and hair loss follow.
Lice cling to skin (slow but hard to catch); white eggs in fur and black specks (flea dirt, digested blood) that turn red in water confirm fleas—and likely tapeworm, since fleas carry it. Never crush a flea with a fingernail; the burst can spread tapeworm eggs to you.
Ticks peak in spring/summer on grass and bushes; a bite may look like a bean-sized blood blister. Don’t yank it—use a topical tick product so it detaches, or see a vet (tick-borne babesiosis is possible).
2 Internal Parasite Signs
Dull coat suggests poor nutrient absorption; pale (not pink) gums signal anemia, often parasitic. Check gums by lifting the lip.
Tarry dark-red stool, frequent vomiting, appetite loss/weight drop, a swollen belly, and lethargy all point to internal worms stealing nutrients.
Finding rice- or sesame-sized white packets, flat cream segments, or spaghetti-like worms in stool or around the anus confirms infection. Consult an online vet for a prescription, or get a fecal/antigen test at a clinic.
