Cherries

Symptoms reported in cats

Most serious first.

1. 1
   Difficulty Breathing and Hyperventilation Rapid onset (often within minutes to a few hours). · The hydrogen cyanide released from crushed cherry pits, stems, or leaves acts directly to inhibit cellular oxygen metabolism1. This forces the cat to hyperventilate and gasp for air as its body attempts to compensate for the sudden inability of its cells to extract and utilize oxygen.
2. 2
   Convulsions, Seizures, and Twitching Rapid onset. · Because the brain is a high-oxygen-demand organ, the sudden halt in ATP (energy) production caused by cyanide poisoning quickly deprives the brain of energy, leading to profound neurological distress and involuntary motor dysfunction.
3. 3
   Coma and Shock Rapidly following respiratory distress and seizures. · As the cyanide completely halts cellular respiration in vital organs, the resulting rapid cellular death in the brain and heart leads to cardiovascular collapse, loss of consciousness, coma, and ultimately death if untreated.
4. 4
   Cherry-Red Mucous Membranes Rapid onset. · Because cyanide blocks the cells from taking up oxygen from the bloodstream, venous blood remains fully saturated with oxygen. This causes a distinct, abnormally bright red coloration of the cat's skin, gums, and mucous membranes.
5. 5
   Gastrointestinal Obstruction (Physical Hazard) Variable (can take hours to days for symptoms like persistent vomiting and severe abdominal pain to · Aside from chemical toxicity, swallowing an intact, hard cherry pit presents a major physical hazard. The undigested pit can become lodged in the cat's digestive tract, causing a dangerous mechanical obstruction.
6. 6
   Vomiting and Diarrhea Shortly after ingestion (often within 30 minutes to a few hours). · This can occur as an initial reaction to the cyanide toxicity or due to the physical irritation of the plant material and seeds passing through the digestive tract.

Important notes

The safety of cherries for cats depends on the part of the cherry. The ripe flesh, with the pit removed, is not clearly toxic, and a very small amount usually does not cause serious problems. However, cherries are high in sugar and may still cause digestive upset, so they are not recommended as a treat. The real danger comes from the pit, stem, leaves, and bark. These parts contain amygdalin, which can be broken down in the body and produce cyanide. Cyanide interferes with the cells’ ability to use oxygen, preventing the body from producing energy properly. This can quickly affect the heart, brain, breathing, and nervous system. If a cat bites into or swallows a cherry pit, or eats the stem, leaves, or bark of a cherry plant, it should be treated as a poisoning risk. Contact a veterinarian as soon as possible.

• Symptoms (if pits or leaves ingested): Vomiting, rapid or laboured breathing, lethargy, low blood pressure, shock, seizures, and potentially fatal cardiac and respiratory failure.
• Safe part: Pitted ripe flesh only — fully remove pit, stem, and any leaves before offering a small piece as a treat.
• Physical hazard: Pits pose a choking and intestinal obstruction risk even before releasing cyanide.
• Action: Emergency veterinary care if pit, bark, or leaves have been chewed.
