Is english walnut 'tulare' safe for cats and dogs?
Mildly. The ASPCA flags english walnut 'tulare' as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. The ASPCA does not list English walnut (Juglans regia) among toxic plants, and the ripe sweet kernels are not considered poisonous to cats and dogs. However, the genus produces juglone, and moldy walnuts and hulls can harbour tremorgenic mycotoxins (penitrem A) that cause tremors and seizures in dogs; the high fat content also risks pancreatitis. Keep fallen and moldy nuts away from pets and verify with a vet if ingestion occurs.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |
