Short answer
Yes, snap peas are safe for cats with kidney disease. They are low in phosphorus and sodium, which makes them a suitable occasional treat for kidney-compromised pets. Just ensure the peas are plain and cut into small pieces to prevent choking. Monitor your cat for any digestive upset, though this is unlikely with such a small amount.
