No, cats should not eat guacamole, and it’s safest to treat it as off‑limits for your kitty.

Quick Scoop

Guacamole is risky for cats for several reasons:

  • Avocado (persin toxin): Avocado contains persin, which can upset a cat’s stomach and, in larger amounts, potentially cause more serious issues like vomiting and diarrhea.
  • Onion and garlic: Many guac recipes include onion and/or garlic, which are highly toxic to cats and can damage red blood cells and cause anemia even in relatively small amounts.
  • Lime and other citrus: Lime juice and other citrus ingredients can irritate the digestive tract and may cause neurological signs if enough is eaten.
  • Spices, chili, and salt: Hot peppers, spices, and excess salt can cause stomach pain, vomiting, diarrhea, and dehydration.

Because guacamole usually combines several of these at once, vets and pet- nutrition sources consistently recommend that cats never be given guacamole on purpose.

What if my cat already ate some?

If your cat just had a tiny lick, they will often be okay but you still need to watch them closely for the next 24 hours.

Look for:

  • Vomiting or diarrhea
  • Lethargy, weakness, or not wanting to eat
  • Drooling, fast breathing, or looking “off”
  • Very pale gums or wobbliness (emergency signs)

If they ate more than a small taste, if your guac had onion or garlic, or if you notice any symptoms, contact a vet or emergency clinic right away and tell them exactly what ingredients were in the guacamole and roughly how much your cat ate.

Safe treat ideas instead

If you want to share something “special” with your cat, skip the guac and try:

  • Plain cooked chicken or turkey (no seasoning, no bones)
  • Small bits of plain cooked fish (no sauce, no onion/garlic)
  • Vet‑approved commercial cat treats formulated for their nutritional needs

These options give your cat a fun snack without the toxin and tummy‑upset risks that come with guacamole.

TL;DR: Can cats eat guacamole? No—because of avocado toxins, onion/garlic, citrus, spices, and salt, it’s a hard “don’t share,” and you should call a vet if your cat has eaten more than a tiny taste.
