Locust trees, also known as black locust or false acacia, are not typically allergenic to cats. However, these trees can be mildly toxic to felines if ingested. Locust trees contain compounds called robin, phasin, and other cytotoxic proteins that can cause gastrointestinal upset and other symptoms in cats.
These deciduous trees are commonly found in parks, along streets, and in landscaped areas across North America and Europe.
Ingestion may cause mild gastrointestinal upset, but is generally not life-threatening.
Ingestion can result in mild symptoms like vomiting, diarrhea, or drooling. Rarely fatal but may require veterinary care.
Eating these plants can lead to more pronounced symptoms like abdominal pain, lethargy, or difficulty breathing. Veterinary intervention may be necessary.
Ingesting even small amounts can cause severe symptoms like organ damage, seizures, or cardiac failure without rapid treatment.
All parts of these plants are extremely poisonous to cats and can quickly lead to death, even with immediate veterinary care.
** Please note: Please note that toxicity level can vary based on the amount ingested and the specific cat. It's always best to keep these plants completely inaccessible to cats and seek immediate veterinary care or call the poison hotline if you suspect your cat has ingested any part of a toxic plant.
If a cat ingests parts of a locust tree, such as the bark, leaves, seeds or seedpods, they may experience symptoms of toxicity. Common signs include:
In most cases, symptoms are mild and self-limiting. However, if a cat consumes a large amount of locust tree material, more severe reactions like seizures, tremors, or breathing difficulties are possible. If you suspect your cat has eaten any part of a locust tree and is showing symptoms, contact your veterinarian right away.
If you bring your cat to the vet after they have ingested parts of a locust tree, here are the steps the vet may take to diagnose and treat the toxicity:
With prompt treatment, the prognosis for locust tree ingestion in cats is generally good. Most cats recover fully within 24-48 hours with supportive veterinary care.Learn more about treating locust poisoning in cats.
A: Locust trees, particularly the black locust, are highly toxic to cats. If a cat ingests any part of the tree, it can result in serious symptoms like vomiting, diarrhea, and even life-threatening conditions.
A: Yes, black locust trees are extremely toxic to cats, and all parts of the tree, including leaves and bark, can cause poisoning. Symptoms may include nausea, vomiting, weakness, and difficulty breathing.
A: The black locust tree contains toxic compounds like toxalbumins, making it dangerous to both animals and humans. Ingesting parts of the tree can cause gastrointestinal distress and, in severe cases, nervous system disorders.
A: Most animals, including cats, should not consume black locust as it is highly poisonous. While some wildlife like deer and squirrels might eat parts of the tree, it is unsafe for domestic pets like cats.
A: Unlike the black locust, the honey locust tree is not toxic to cats. However, the sharp thorns on the tree can cause physical injuries to pets.
A: Locust bugs are generally not toxic to cats. However, it’s best to avoid allowing your cat to consume them, as insects may carry parasites or cause digestive upset.
The black locust tree is native to the Appalachian Mountains and Ozark Plateau regions of North America. It was first described botanically in the early 1700s. The tree was named “Robinia” after Jean Robin, herbalist to French kings in the 1600s. His son planted this tree in Paris in 1636.
Black locust has been widely planted as an ornamental and naturalized across temperate regions worldwide. The rot-resistant wood is valued for its durability. However, the tree is considered invasive in some areas due to its ability to spread rapidly through root suckers and seeds. It can form dense groves that crowd out other vegetation.
While not a significant allergen itself, the pollen from locust tree flowers may contribute to seasonal allergies in people who are sensitive. The tree blooms in late spring with fragrant white flowers.
