Why?
The peach pit, like the leaves and stems, contains amygdalin, which releases cyanide when chewed or cracked. Swallowed whole, that big pit can also get stuck in the esophagus or intestines. The flesh alone isn't toxic, but it's sugary and does nothing for your cat, so to be safe, the rule is not to share.
How much?
No amount is recommended. A lick of flesh is nothing serious, but never leave pits, branches or peach leaves lying around.
The risks
- Pit, stem and leaves contain cyanogenic compounds
- Swallowed pit: blockage of the esophagus or gut
- Bright red gums, dilated pupils, trouble breathing
- Vomiting and diarrhea
Your cat ate some: what now?
If your cat chewed or swallowed a pit, leaves or a stem, call your vet or an animal poison control center right away, without waiting for symptoms. Don't try to make your cat vomit yourself: a pit can get stuck on the way back up. If your cat only licked some flesh, watch for stomach upset over the next 24 to 48 hours.
Better options
For a small, safe sweet bite, two or three blueberries do the trick. Even better: a small piece of plain cooked chicken or a cat treat.
Common questions
My cat licked a piece of peach, is that bad?
No, the flesh alone isn't toxic. The pit, leaves and stem are the problem: just make sure your cat didn't get to them.
What about nectarines or canned peaches?
Nectarines have exactly the same issues, pit included. Canned peaches in syrup are far too sugary: avoid them too.
