Is Bishop Weed Toxic To Cats? 

Bishop’s weed, also known for its other common names Greater Ammi and False Queen Anne’s Lace, is commonly found in gardens and in the wild but found to be toxic for cats. Insoluble calcium oxalates and furanocoumarins are the poisonous components found in bishop’s weed. Furanocoumarins induce significant photosensitivity in your cat’s skin, which spreads to all of their external organs, including their eyes. Cats experiencing Bishop’s weed poisoning can have permanently damaged corneas that can lead to blindness in severe cases.

Proper and immediate veterinary care is essential in any type of poisoning in cats. Do not give any medication or perform any procedure at home without consulting your veterinarian.

To remove any lingering toxins from your cat’s system, the veterinarian will most likely induce vomiting. Your cat can be given activated charcoal to absorb harmful residues in his stomach and expel them through his stool. The veterinarian may also perform gastric lavage if necessary. Your veterinarian may hold your cat for a few days for additional observation depending on the severity of the bishop weed poisoning.

Recovery from Bishop Weed Poisoning in Cats

Most cats recover well from bishop’s weed poisoning if treated quickly. For a period of time, your cat will need to be kept indoors and away from bright light until the poison has been digested and cleared from his system. A follow-up visit to the veterinarian is essential to ensure that your cat’s organs are functioning properly and that they are not experiencing any extra side effects. Your cat should be able to recover completely with adequate care.
