The Short Answer
Can cats eat eggnog? No. Eggnog should be kept away from cats. This rich holiday drink combines several ingredients that are bad or outright dangerous for felines: lactose-heavy dairy, raw egg, heavy sugar, toxic nutmeg, and very often alcohol. Even a few licks can upset a cat’s stomach, and a larger amount can cause serious harm. There is no safe serving of eggnog for cats.

During the holidays, it is easy for a curious cat to sneak a taste from an unattended glass left on a side table or counter. The creamy smell can be appealing, and cats are notorious for investigating drinks. The best approach is to keep eggnog well out of reach entirely and to clean up any spills right away.
Why Eggnog Is Dangerous for Cats
Eggnog is a perfect storm of ingredients that do not belong in a cat’s diet. Each one adds its own risk, and together they make eggnog one of the riskier holiday foods for cats:
- Dairy and lactose: Most adult cats are lactose intolerant. Milk and cream can cause vomiting, diarrhea, and gas.
- Raw egg: Traditional eggnog uses raw egg, which can carry Salmonella and contains avidin, a protein that interferes with biotin absorption.
- Sugar: Cats cannot taste sweetness and gain nothing from sugar. Excess sugar contributes to obesity and dental issues.
- Nutmeg: Nutmeg contains a compound called myristicin that is toxic to cats and can cause symptoms ranging from stomach upset to disorientation.
- Alcohol: Many eggnog recipes include rum, brandy, or bourbon. Alcohol is highly toxic to cats even in tiny amounts.
Any one of these would be reason enough for caution. Together, they make eggnog a clear avoid. Even store-bought, non-alcoholic eggnog still contains the dairy, sugar, and nutmeg that cause trouble, so a commercial carton is no safer than a homemade batch.
The Nutmeg and Alcohol Risk
Two ingredients deserve special attention. Nutmeg is genuinely toxic to cats. In larger amounts it can cause increased heart rate, high blood pressure, dry mouth, abdominal pain, and even hallucinations or seizures. You can read more about why nutmeg is harmful to cats and why spiced foods in general are risky for them.
Alcohol is even more dangerous. Cats are far smaller than people, so a quantity that seems trivial to us can cause vomiting, breathing problems, loss of coordination, and dangerous drops in body temperature and blood sugar. Spiked eggnog should be treated as an emergency hazard. Because the creamy texture of eggnog masks the taste of alcohol, a cat may readily lap up a spiked version without hesitation.
It is worth remembering that the alcohol risk is not limited to obvious drinks. Even a splash of spiked eggnog in a cat’s bowl, or a glass left where a cat can reach it, can deliver a harmful dose to a small animal.
To put the nutmeg risk in perspective, the amount in a single cup of eggnog is small relative to a person, but a cat is a fraction of a human’s body weight, so the same pinch represents a far larger relative dose. The compound myristicin affects the nervous system, which is why disorientation and a racing heart can accompany the more familiar stomach upset. While a tiny lick is unlikely to cause severe nutmeg poisoning on its own, the spice is one more reason that eggnog earns a firm avoid rather than a cautious maybe.
What to Do If Your Cat Drinks Eggnog
If your cat laps up a small amount of plain, non-alcoholic eggnog, watch for digestive upset like vomiting or diarrhea over the next several hours. Provide fresh water and monitor closely. Mild stomach upset from the dairy and sugar is the most likely outcome, but keep an eye out for anything more serious.
If the eggnog contained alcohol, or if your cat consumed a larger amount, contact your veterinarian or an emergency animal clinic right away. Signs that warrant immediate care include:
- Stumbling, weakness, or loss of coordination
- Disorientation or unusual behavior
- Rapid breathing or heart rate
- Tremors or seizures
- Repeated vomiting or collapse
- Unusually low energy or unresponsiveness
When in doubt, call your vet. It is always better to ask than to wait, especially with ingredients as serious as alcohol and nutmeg. If you can, note how much your cat drank and whether the recipe was spiked, since that information helps your vet assess the risk quickly.
Why Cats and Dairy Drinks Do Not Mix
Many people picture cats happily lapping milk, but that image is misleading. Kittens produce the enzyme lactase to digest their mother’s milk, but most cats lose much of that ability as they grow. By adulthood, the majority of cats are lactose intolerant, meaning dairy ferments in their gut and causes gas, bloating, and diarrhea.
Eggnog amplifies this problem because it is built on cream and milk, often with added condensed or evaporated milk for richness. So even setting aside the nutmeg and alcohol, the dairy alone is enough to upset most cats’ stomachs. This is a good reminder that creamy holiday treats are simply not designed for feline digestion.
The raw egg in traditional eggnog adds a separate problem on top of the dairy. Beyond the risk of Salmonella, raw egg white contains a protein called avidin that binds biotin and can interfere with its absorption over time. A single exposure is not going to cause a deficiency, but it underscores that the egg in eggnog is not the safe, cooked egg a cat could otherwise tolerate. Commercial cartons may use pasteurized egg, which lowers the bacterial risk, but they keep all the sugar, lactose, and nutmeg that make the drink unsuitable regardless.
Keeping Drinks and Desserts Out of Reach
Eggnog is usually served in open cups and punch bowls, often left sitting on coffee tables, counters, and sideboards during gatherings. That is exactly the kind of situation where a curious cat can sneak a lick before anyone notices. Cats are agile and inquisitive, and a creamy, fragrant drink is an obvious target.
During holiday parties, ask guests to keep their drinks elevated or covered, and clear empty glasses promptly rather than leaving them within a cat’s reach. Be especially mindful of spiked eggnog, since the alcohol risk is serious and the creamy texture hides the taste that might otherwise warn a cat off.
It can also help to give your cat a quiet, separate room during a party, complete with their own food, water, and a comfortable spot to rest. This not only keeps them away from risky foods and drinks but also spares a nervous cat the stress of a busy, noisy household. A little planning lets everyone, including your cat, enjoy the celebration safely.
Pay attention to where empty and half-finished glasses end up, too. Guests often set drinks down on low coffee tables, the floor beside a chair, or a windowsill, all easily within a cat’s reach. The creamy residue left in a glass is just as appealing to a cat as a full cup, and a spiked leftover can still hold enough alcohol to matter for a small animal. Doing a quick sweep for stray glasses during and after the gathering removes a hazard that is easy to overlook in the bustle of a celebration.
Safe Holiday Treats for Cats
Your cat does not need to miss out on the holidays. Instead of risky human foods, offer a small bite of something carnivore-friendly. Plain cooked chicken or turkey makes a festive, safe treat your cat will actually enjoy and that suits their carnivore biology.
If your cat is curious about eggs, learn how to safely offer cooked eggs, which are fine when fully cooked and plain. The cooking eliminates the Salmonella and avidin concerns that make raw egg in eggnog risky. Just steer clear of holiday dishes loaded with dairy, sugar, and spices.

Frequently Asked Questions
Can cats have a small lick of non-alcoholic eggnog?
It is best to avoid it entirely. Even alcohol-free eggnog contains lactose, raw egg, sugar, and nutmeg, all of which can make your cat sick.
What if my cat drank eggnog with alcohol in it?
Contact your veterinarian or an emergency clinic immediately. Alcohol is highly toxic to cats and can cause serious, rapid harm even in small amounts.
Is the nutmeg in eggnog really toxic to cats?
Yes. Nutmeg contains myristicin, which is toxic to cats and can cause stomach upset, a racing heart, disorientation, and in larger amounts seizures.
My cat loves milk. Can I give plain milk instead of eggnog?
Most cats are lactose intolerant, so even plain milk can cause digestive upset. Fresh water is the safest drink, and a complete cat food provides all the nutrition they need.
Are there cat-safe holiday drinks?
The safest drink for any cat is fresh water. If you want to celebrate, offer a small bite of plain cooked meat rather than any festive beverage.
What about dairy-free or vegan eggnog?
Plant-based eggnog avoids the lactose problem, but most versions still contain heavy sugar and nutmeg, and some include other spices. The sugar and nutmeg alone make it unsuitable, so a dairy-free label does not make eggnog a cat-safe drink.
How long after drinking eggnog might symptoms appear?
Mild digestive upset from dairy and sugar often shows within a few hours. If alcohol was involved, signs like wobbliness or unusual behavior can appear quickly and warrant an immediate call to a vet. Keep watching for several hours after any ingestion.
