What to do after ingestion
Vomiting, loose stools; chronic large amounts are linked to urinary stone risk.
A small taste only needs observation; ask a vet if the cat has a urinary history.
Cats are obligate carnivores, so spinach offers no required nutrition and contains oxalate; with urinary disease common in cats, it is best avoided.
What to do after ingestion
Large amounts may cause stomach upset (vomiting, loose stools); chronic excess is associated with higher urinary oxalate.
A small amount only needs observation; contact a vet if a pet with a stone or kidney history ate a larger quantity.
Spinach is high in oxalate, which binds calcium and reduces its availability; dogs with calcium oxalate stones or kidney disease should avoid it entirely, and healthy dogs should only have very small amounts.

Cooking reduces some but not all oxalate; other vegetables (carrot, pumpkin, green beans) are better choices.
