How Their Bodies Use It
Since cats are 'obligate carnivores,' their bodies are naturally built to get almost all their nutrition from meat. They don't actually have a need for fruits or vegetables. When a cat eats onions, their body has to decide how to use those specific nutrients. Vegetables like onions provide 'roughage' or fiber. For many small pets, this fiber is vital for keeping their tummy moving and healthy. However, some veggies have specific minerals (like calcium or oxalates) that need to be limited to prevent bladder or kidney issues.
How to Serve It Safely
If you decide to give Onions to your pet, here is the safest way to prepare it:
- Wash it very well to remove any dirt or sprays (pesticides) from the farm.
- Start with a tiny 'tester' piece to make sure it doesn't upset their stomach.

Lethargy, pale or yellowish gums (jaundice), weakness, rapid heart rate, and dark/reddish urine. Seek veterinary care immediately. -
