Cats often show interest in human food. Oranges look bright and smell strong. But are they safe for cats? No. Oranges harm cats. This guide covers why. It lists risks. It gives steps if your cat eats one. It shares safe options too.
Why Oranges Harm Cats
Oranges belong to the citrus group. All citrus fruits pose risks to cats. Cats must eat meat. Their bodies handle meat well. Plant foods like fruit can cause problems.
Toxic Parts in Oranges
Oranges have compounds that hurt cats. These include essential oils. Limonene and linalool sit in the peel. They upset the stomach. They affect the nervous system too.
Psoralens hide in the peel and seeds. They make skin sensitive to light. This leads to burns or rashes.
Citric acid fills the fruit. It irritates the gut. Cats feel pain from it.
The whole orange causes issues. Peel holds the most toxins. Flesh has less. But even flesh brings high sugar. Cats process sugar poorly. It leads to weight gain or other health woes.
No Health Gains for Cats
People eat oranges for vitamin C. Cats make their own vitamin C. They need no extra. Fiber in oranges helps humans. But cats get little use from it. Their short guts suit meat, not plants.
Sugar in oranges spikes blood levels. This risks diabetes in cats.
Signs Your Cat Ate an Orange
