The short answer: Because they have eyeballs!
Do you ever wake up with a little bit of crusty goop in the inner corner of your eyes? Your eye boogers are a normal accumulation of different things, like dried tears and mucus. Cats get that crusty morning gunk as well. So long as there aren’t mounds of it, and your cat’s eyes are bright and clear, there’s no reason to panic.
But watch out for lots and lots of goop
If your cat’s eye boogers are a thick yellow or green, that’s definitely not normal, and could point to an eye infection.
When to worry about eyeball boogers
Thick yellow or green eyeball crud are signs that something unhappy is happening to your cat’s eyes. Typically, cat eye infections are caused by bacteria, which is more likely to cause infections when your cat’s eyes or general immune system is weakened or vulnerable. This can be caused by:
- Viral infections like feline herpesvirus-1
- Conjunctivitis (inflamed connective tissues in the eye)
- Dry eye
- Something in the eye
- Corneal injury
- Long facial hairs irritating the eyes
- Eyelids that fold inward (entropion’) or outward (ectropion)
- Other health conditions, such as allergies and upper respiratory infections
