The verdict for dogs
Both spinach and kale are caution for dogs. Spinach contains oxalates, which can interfere with calcium absorption and cause kidney issues with regular consumption. On kale: Contains calcium oxalate and isothiocyanates — large amounts may cause bladder/kidney issues.
The verdict for cats
Both are caution for cats. Remember cats are obligate carnivores — even safe plant foods are treats, not staples.

Why this matters
