Cat ticks are spider-like, egg-shaped, blood-sucking creepy crawlies that can vary significantly in appearance depending on their life stage and whether they have fed. Adult ticks look a bit like small spiders, ranging in size from about 1mm when unfed to over 1cm long when engorged with blood.
Key Characteristics of Cat Ticks
Understanding the distinct features of cat ticks can help with early identification and removal.
Size and Shape
- Unfed: Ticks are typically small, flat, and teardrop or oval-shaped, about 1mm to 5mm in length, resembling a tiny sesame seed or poppy seed.
- Engorged: After feeding, they become much larger, distended, and more rounded, often growing up to 1cm or more. Their color can change dramatically, appearing grey, bluish-grey, or yellowish-white as they fill with blood.
Legs
Cat ticks possess six to eight legs, depending on their life stage:
- Larvae: Have six legs.
- Nymphs and Adults: Have eight legs, similar to spiders. These legs are usually dark and concentrated towards the front of their body.
Color and Texture
- Unfed: Common colors include brown, reddish-brown, black, or tan. Their bodies are relatively flat and leathery or waxy.
- Engorged: As mentioned, they often become lighter in color (grey, blue, or white) and take on a smoother, more taut appearance due to the blood meal.
Summary of Visual Traits
Here's a quick overview of what to look for:
| Characteristic | Unfed Tick | Engorged Tick |
|---|---|---|
| Shape | Flat, oval, or teardrop | Rounded, swollen, grape-like |
| Size | 1mm – 5mm (poppy seed to sesame seed size) | Up to 1cm or more (pea to small grape size) |
| Color | Brown, reddish-brown, black, tan | Grey, bluish-grey, yellowish-white, lighter brown |
| Legs | 6 (larvae) or 8 (nymphs/adults) | 6 (larvae) or 8 (nymphs/adults) |
| Texture | Leathery, waxy | Smooth, taut, shiny |
What to Look For on Your Cat
Ticks often attach in areas where they can feed undisturbed and are harder for the cat to groom. Regular checks of your cat are crucial, especially after they have been outdoors.

Common Attachment Sites:
- Around the head, ears (especially inside and behind), and neck.
- Under the chin and around the muzzle.
- In the armpits and groin area.
- Between the toes and on the paw pads.
- Under the tail.
-
Detection Tips:
- Run your hands over your cat's fur, feeling for any small bumps or abnormalities.
- Part the fur to get a clearer view of the skin, particularly in dense fur areas.
- Pay attention to any scabs, redness, or irritation that might indicate a tick bite.
Why Identification Matters
Accurate identification of a tick allows for proper removal and helps in monitoring your cat for any signs of tick-borne diseases. Early removal can significantly reduce the risk of disease transmission, as many pathogens require several hours of feeding to be transmitted to the host. For more information on tick-borne illnesses and prevention, consult resources from reputable organizations like PetMD or VCA Hospitals.
