Although it's common to hear stories of dogs getting sick from chocolate ingestion, chocolate can also pose a serious health risk to cats, even becoming fatal if too much is eaten.
Why Is Chocolate Bad for Cats?
Sugar, fat, and xylitol (a sugar substitute) aren't good for cats. However, chocolate contains two ingredients that pose a bigger threat to your cat’s health: caffeine and theobromine, a plant alkaloid that occurs naturally in cacao. Theobromine in particular is a proven toxin for most animals, including cats, as noted by the Merck MSD Veterinary Manual.
The Latin name for the cocoa plant is Theobroma cacao, meaning "food for the gods". It’s true that the roasted beans do make a yummy treat, but what makes chocolate so delightful for humans is exactly what makes it so dangerous for cats.
Why Are These Ingredients so Dangerous for Cats?
The two main culprits, caffeine and theobromine, are stimulants. Caffeine, found in many food and drink items besides chocolate, becomes toxic when absorbed into your cat's body. Cats Protection explains that theobromine acts as a stimulant to increase your cat’s heart rate, and as a diuretic to increase the loss of bodily fluids, both of which can prove fatal for your furry friend.
How Much Chocolate Is Too Much?
Any amount of chocolate is too much for your cat. Cats Protection explains that cats can’t process theobromine as quickly as we can so it stays in the body for longer. That means that even a couple of grams of chocolate can cause serious harm.
All forms of chocolate are hazardous to your furry friend. Baking chocolate is most toxic due to its high level of theobromine, but dry cocoa powder and dark, semi-sweet, and milk chocolate are also dangerous. Even white chocolate, with its low percentage of cocoa, should be avoided.
Help — My Cat Ate Chocolate! What Symptoms Should I Watch For?
Chocolate toxicity in cats can range from mild to severe. Here are some of the main signs and symptoms to look out for:
- Increased heart rate
- Excessive thirst
- Excessive urination
- Increased body temperature
- Rapid breathing or panting
- Muscle tremors or twitching
- Low blood pressure
As you would with any medical emergency, immediately bring your cat to the vet to determine the extent of the poisoning and to receive treatment. After treatment, continue to monitor your cat for any other ill effects.
What Happens Next?
Your cat is very in-tune with your emotions so remain as calm as possible. Take them to a quiet place and keep them cool and calm to prevent the symptoms of chocolate poisoning from escalating.
Once you arrive at the vet clinic, the veterinarian will examine your cat and assess the amount and type of chocolate your cat has eaten. The vet may want to induce vomiting to help prevent your cat from absorbing the toxins, and will provide fluids and additional care depending on the amount of chocolate consumed and the side effects your cat is experiencing.
How Do I Prevent This from Happening?
Chocolate ingestion is 100% preventable by keeping chocolate out of paw's reach. Cats are curious, unpredictable creatures and love to snoop around the kitchen, so secure all chocolate in a tightly sealed container. It's not just chocolate bars that can make them sick, so think of all the things that might contain chocolate, including brownies, doughnuts, biscuits and sweets. This is especially true around holidays like Easter, Christmas and Halloween. If you're entertaining, place sweet dishes, desserts and treats in places that are difficult for your cat to reach and store them securely immediately after the party. If a guest asks, "can your cat eat chocolate?", you are now prepared to answer with a resounding "no".
Pet parents do like to treat their feline friends, and you can do so safely by sticking to safe cat treats, created to keep your cat happy and healthy. Then you get to keep the chocolate all to yourself!
