 When talking about if cats are allowed to eat albacore tuna or not? So the answer is NO!

  • Wash it thoroughly first and then cooked it well without adding any flavors 
  • Make sure that it’s boneless because extra bones can get stuck in your cat’s throat.

Can tuna also be offered to your cat but make sure that it’s water-packed tuna without any additives or chemicals.
