Yes, cats can eat sardines! Sardines are one of the safest and most nutritious fish for cats, with the advantage of having less mercury than larger fish like tuna.

Benefits of sardines for cats

  • Omega-3 (EPA and DHA) — anti-inflammatory, benefits skin, coat, and joints
  • Quality protein — essential for obligate carnivores
  • Taurine — vital amino acid for cats’ heart and vision
  • Calcium and phosphorus — present in the bones (whole sardines)
  • Vitamin D — important for bone health
  • Low mercury — sardines are small fish that accumulate fewer toxins

Usage tips

  • Stimulate appetite: mix a little sardine into cat food if your cat is off their food
  • Hydration: the broth from sardines in water can be offered to cats who don’t drink enough
  • Natural supplement: sardines are a natural source of omega-3, an alternative to supplements

Precautions

  • Don’t replace cat food: sardines don’t have all necessary nutrients
  • Watch the sodium: always prefer the no-salt-added version
  • Bones: canned sardine bones are soft and safe, but large fresh sardines may have dangerous bones
  • Too much fish: a diet based solely on fish can cause vitamin E deficiency
