Exploring new things is an instinct that helps kitties survive in the wild, but can this trait cause them harm in our homes, especially when it comes to certain foods?  So, can cats eat lemon? We explain what happens if a cat eats a lemon, the symptoms to watch out for and what you should do.

Lemon poisoning can be fatal in cats. The severity and signs of lemon poisoning will depend on how much lemon your cat has consumed.

What happens if a cat eats lemon?

If your cats eats any part of a lemon, you must contact your vet immediately as poisons act quickly. Do not be tempted to try and make your cat sick as this can aggravate the situation and cause more damage to your feline. Instead, remove the lemon to ensure your kitty doesn’t eat anymore and take it with you so your veterinarian can perform the relevant tests. When a cat is sick they often like to hide and act differently to how they normally do. The quicker you seek professional help, the more likely your cat will make a good recovery.

The treatment of lemon poisoning in cats will depend on whether they have consumed lemon or got some on their skin or paws. If your kitty has skin irritation from lemons, your veterinarian will give him a bath to wash the toxins off and soothe the skin. If your cat has ingested lemon then the treatment options may include a stomach wash to flush out any toxins that could cause harm.

Your pet will require constant monitoring after treatment in case they become dehydrated, which may require an IV fluid drip.

A cat’s nose is its most important sense organ that contains 200 million scent receptors.

Just like dogs, cats generally hate the smell of all citrus fruits as the strong smell can offend sensitive noses, but that may not be enough to stop them from taking a lick. Even though they hate the smell, their inquisitive nature may tempt them into tasting the offensive object.

Can cats have lemon and pepper?

As we now know, if a cat consumes or comes into close contact with any part of a lemon, it can cause harm as it contains toxins.

Pepper contains piperine which irritates a cat’s sense of smell. Therefore, feeding your cat a combination of lemon and pepper will put your feline at risk of lemon poisoning which can be severe and even fatal.

Should Cats Eat Lemon

What about lemon-flavored water and foods?

Lemon water has traditionally been used as a natural flea treatment by spraying a cat’s fur with a mixture of lemon and water. Whilst spraying your cat with lemon water is less harmful than your cat drinking it, this method comes with risks as we all know how much cats enjoy licking themselves clean and even a small amount of lemon can make your cat very ill.

It’s safest to prevent your cat from coming into contact with all lemon-flavored foods and drink.
