My 4-year-old cat swallowed several pear seeds while eating chicken stew — what should I do now?

Short answer

This is urgent. Pear seeds contain amygdalin, which converts to cyanide when chewed or crushed in the stomach. Several seeds swallowed from stew are a real concern, especially if the cat chewed them. Watch for dilated pupils, bright red gums, difficulty breathing, or collapse — these are signs of cyanide poisoning that can worsen rapidly. Call the ASPCA Poison Control line at 888-426-4435 immediately or take her to an emergency vet now. Do not wait to see if she seems fine later.

Why chicken stew changes the poisoning timeline

The fats and proteins in stew can delay stomach emptying, which means seeds may remain in contact with digestive acids longer — this extends the window for amygdalin conversion to cyanide. A cat that ate seeds with plain water might process them faster than one who consumed them with a heavy, meat-based liquid.

Watch for vomiting that smells like almonds (a hallmark of cyanide release), but don't induce it. The stew's moisture content also matters — well-cooked seeds in broth may have started breaking down already, increasing their surface area for toxin release compared to dry seeds.

How many seeds cross the danger line for 4-year-olds

While there's no safe number of pear seeds for cats, the risk escalates sharply after two or three crushed seeds for an average-sized adult. Your cat's age puts her in prime health for fighting toxins, but that doesn't eliminate risk — it just means symptoms may appear later than in kittens or seniors.

The real variable is whether she crunched the seeds or swallowed them whole. Listen for unusual chewing sounds if it happened recently, or check her stool over the next 24 hours for seed fragments. Intact seeds pose less risk than fragmented ones, but stew cooking may have pre-softened them.

The first six hours after seed ingestion

Initial signs often mimic other issues — slight pawing at the mouth could indicate oral irritation from seed fragments rather than systemic poisoning. But as cyanide builds, look for a progression from mild distress to obvious neurological signs: first pacing or restlessness, then stumbling, then inability to stand.

Breathing patterns tell the story — early rapid breaths shift to slow, deep gasps as oxygen utilization fails. Gums may initially pale from shock before turning alarmingly red as blood oxygen drops. Keep her in a quiet, cool space to reduce metabolic demands while you monitor.

When home observation isn't enough

If the stew contained alcohol (like wine or brandy) or onions, these compound the risk — both substances stress the same detox pathways cyanide overwhelms. Likewise, any previous exposure to smoke inhalation or carbon monoxide makes cats more vulnerable to oxygen-carrying disruptions.

Don't wait for all symptoms to appear. If she pants without exertion, vocalizes unusually, or can't settle into her normal sleeping positions, these are subtle but serious red flags. Have your vet's number ready and note exact ingestion time — antidote effectiveness depends on precise timing.
