How much orange for your cat?
Most guides say "a few pieces". Enter your cat's weight and get the actual daily ceiling, worked out from orange's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for cats
Cats dislike citrus and the oils and acidity can cause stomach upset, so orange is best avoided.
A segment or two of peeled orange is safe for most dogs — vitamin C and hydration in a sweet package. Most cats, on the other hand, are actively repelled by citrus, and that instinct serves them well.
How much is safe?
One or two peeled, seedless segments for a dog, occasionally. The sugar adds up fast, so keep it small — and skip it for diabetic or overweight pets. For cats, don't bother: most refuse citrus, and the oils in the peel are irritating to them.
What happens if a cat eats too much?
Too much orange means a sugary, acidic stomach upset — vomiting or loose stool. The peel and pith are hard to digest and can cause blockage in small pets, and citrus oils (concentrated in the peel) are irritating, particularly for cats.
How to serve it safely
Peel completely, remove seeds and as much white pith as possible, and share a segment or two of the flesh only. Skip orange juice — it's the sugar without the fiber.

Frequently asked questions
Can pets drink orange juice?
Better not — it concentrates the sugar and acidity with none of the fiber. Water is always the right drink.
Why do cats hate oranges?
Cats are strongly repelled by citrus scent, and the peel's essential oils are genuinely irritating to them — their aversion is protective.
Are mandarins and tangerines the same deal?
Yes — same rules: peeled, seedless, a segment or two for dogs, occasional only.
