Is Custard Apple toxic to cats?

Annona reticulata

Mildly toxic to cats

Mildly. The ASPCA lists custard apple as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. All Annona species, including A. reticulata, contain annonaceous acetogenins — compounds concentrated in the seeds, bark, leaves, and unripe fruit. These have documented neurotoxic properties linked to atypical Parkinsonism with repeated high-level exposure. Seeds are particularly toxic. Annona is listed as toxic to dogs by veterinary toxicologists. The ASPCA does not specifically list this species, but caution is warranted for all pets. Ripe fruit flesh consumed in moderation is traditional food, but keep seeds and plant parts away from dogs and cats.

What to do if your cat ate custard apple

  1. Remove any plant material from your cat's mouth and move custard apple out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of custard apple to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten custard apple, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
