While your frisky feline may jump in delight and meow to her heart’s content at the sight of an open can of tuna, in all honesty it is not the best option as far as a healthy, well balanced diet goes. Cats may love tuna, some may even be addicted to the fishy goodness however the unfortunate truth is that a steady diet of the fish prepared for humans can lead to malnutrition since it will not have all of the required nutrients your kitty needs.
Too much tuna can also lead to mercury poisoning, a very serious and sometimes lethal condition. A can or pouch of tuna every now and then is okay if given as an occasional treat but just remember to only give it to your cat in moderation. In any case, tuna should never make up more than 5% of your cat’s diet and/or daily calorie intake. Speak to your veterinarian about other dietary options to make the best decision for your cat and keep in mind that your feline friend is an obligate carnivore which means he or she needs a diet that most closely resembles the wild prey they would hunt and devour in the wild.
