What are the tiny black and white bugs -NOT fleas- on my cat?

I can't tell you exactly what kind of tiny black and white bugs are on your cat without seeing them. However, here are some possibilities:

Common culprits:

* Lice: These are tiny, wingless insects that live on the skin and feed on blood. They can cause intense itching and hair loss.

* Mites: These are tiny arachnids that live in the skin and can cause a variety of skin problems. Some common types include:

* Demodex mites: These mites live in the hair follicles and are usually harmless, but they can cause skin problems in cats with weakened immune systems.

* Sarcoptes mites: These mites burrow into the skin and cause a severe skin condition called scabies.

* Cheyletiella mites: These mites live on the surface of the skin and cause a condition called "walking dandruff."

* Fleas: Though you mentioned they are not fleas, it's important to rule them out. Fleas are small, reddish-brown insects that jump and can be difficult to spot.

How to get a diagnosis:

* Take a close look at the bugs: Use a magnifying glass to examine the bugs on your cat's fur.

* Visit your veterinarian: Your veterinarian can examine your cat's skin and identify the bugs.

* Use a microscope: Your veterinarian may use a microscope to examine a skin scraping or hair sample to identify the bugs.

Important note: It's crucial to get a professional diagnosis and treatment for any skin parasites on your cat. Untreated infestations can lead to serious health problems.
