Are tulips toxic to cats (and dogs)?

Tulips bring beautiful colors to your garden. However, cats and dogs aren't exactly big fans of them. This is because tulips are toxic to pets. Unfortunately, this applies to the entire plant, from the leaf to the flower, and especially to the bulb. This is something we always communicate honestly, because no matter how beautiful those bulbs are, you obviously don't want your cat or dog to get sick from them.

In this blog, you will read exactly which parts are dangerous, what you should do if something goes wrong, and which flower bulbs you can safely plant if you have pets.

Are tulips toxic to cats?

Your four-legged friend is worth everything to you. That is precisely why it is good to know that tulips are toxic to cats, even if the animal just nibbles on a leaf for a moment. The toxic substances in the tulip, called tulipalin A and B, can cause symptoms even in small amounts.

We all know: cats are naturally curious animals and love to sneak through the garden. The chance of contact with tulips is greater than you might think. Still want to risk it with tulips? Be extra alert, especially in the fall when the bulbs have just been planted and may still be lying on top of the soil.

Are tulips toxic to dogs?

For dogs, too, it is best to keep tulips out of reach. Dogs are generally a bit less picky than cats, and that makes them more susceptible. They dig up bulbs, chew on stems, or snap at flowers out of pure curiosity. The bulb is the most dangerous part in this regard.

Advice from Brenda

Every autumn, we send thousands of bags of tulip bulbs into the world from the Bollenstreek (Bulb Region). With all our love! And every year, we get the same question back from customers: are those bulbs actually dangerous for my cat or dog? The honest answer is: yes. Because we have animals ourselves, a dog and two cats, we know well that flower bulbs and flowers can be dangerous for animals.

Which part of the tulip is the most dangerous?

What is the reason tulips are toxic to dogs and cats? It has to do with the presence of tulipalin A and B. These substances are present throughout the plant, but the concentration can vary by location. The tulip in order of toxicity:

• The bulb: by far the most dangerous. This is where the highest concentration of tulipalin is found, especially in the outer skins. This is also the part that dogs prefer to dig up and that cats can reach if you have just planted them or leave them in a basket.
• The stem: less concentrated than the bulb, but certainly not harmless. Cats that nibble on a cut tulip will quickly come into contact with this.
• The leaf: also toxic, although the concentration is lower than in the bulb. Still, it is enough to cause symptoms, especially in cats that naturally nibble on plants.
• The flower: the least toxic part, but here too: it is not safe. Even the water in a vase with tulips can contain irritating substances.

Why does the tulip have toxic substances at all?

It is not a coincidence that tulips contain tulipalin A and B. It is a defense mechanism. The plant protects itself against being eaten by animals and insects. The bulb, which is the most valuable part of the plant, contains the highest concentration of these substances. That is also why the outer skins of the bulb are the most toxic: that is the first line of defense.

What are the symptoms if your cat or dog has eaten a tulip?

If a dog or cat has eaten a tulip, you usually notice it fairly quickly. The most common symptoms are excessive drooling, nausea, vomiting, and lethargy. Your pet may also experience diarrhea or even have trouble moving. Be careful! In larger amounts, especially after eating a bulb, heart rhythm disturbances can occur in severe cases.

What should you do if your cat or dog has eaten a tulip?

As soon as you notice that your cat or dog has nibbled on a tulip or dug up a bulb, err on the side of caution and call your veterinarian immediately. Try to indicate as clearly as possible which part of the plant your pet has eaten and how much, as that helps the vet make the right assessment quickly. Do not induce vomiting yourself unless the vet explicitly asks you to. Our advice: Better to call once too early than to intervene too late.

Want to know more about the toxicity of plants?

In the Netherlands, if in doubt, you can also contact the National Poisons Information Center (NVIC) of the UMC Utrecht, which is available 24/7 at 088 755 8000. They provide advice on toxic substances for both humans and animals. Your veterinarian can also contact them for additional advice.

Which other flower bulbs are toxic to cats and dogs?

Besides tulips, there are unfortunately more flower bulbs that can be dangerous to pets. It is good to have a complete picture of this, especially if you are planting a garden full of spring bloomers:

• Daffodils
• Amaryllises
• Hyacinths
• Alliums

Which flower bulbs are safe for dogs and cats?

Do you still want a colorful flower garden without having to worry about your loyal pet? Then it is good to know that there are also flower bulbs that are less or not toxic to cats and dogs. Consider snowdrops and certain species of Scilla, although it is wise to prevent contact with these plants as well. We have a number of these flower bulbs in our assortment of companion plants.

Planting tulips with a cat or dog in the house?

This is how you do it. Safety is most important to us. That is why we are happy to advise you on planting tulip bulbs if you have a cat or dog. Because with a few simple measures, you can simply enjoy a garden full of color without unnecessary risks to your pet. We have collected a number of tips for you.

• Always plant the bulbs deep enough. At a minimum of three times the height of the bulb, which for most tulips is about 10 to 15 centimeters. A well-buried bulb is much less attractive for most dogs to dig up.
• Cover the bed after planting. Place a layer of chicken wire or sturdy netting over the soil and secure it with pegs. This keeps digging-prone dogs at a distance until the bulbs are well-rooted and cannot be easily pulled out.
• Do not leave loose bulbs lying around. Plant the bulbs on the day you take them out of the packaging, or store them in a closed crate in a place your pet cannot reach. Loose bulbs on a garden path or in a bucket are an invitation.
• Wash your hands after planting. The juices from tulip bulbs can also cause skin irritation in humans. Preferably wear gardening gloves and wash your hands well before touching your pet.
• Keep your cat or dog inside during planting. The risk is greatest at the exact moment you are digging and bulbs are lying around you.

We recently wrote an extensive blog about planting tulip bulbs step-by-step. In it, we explain in even more detail how to approach this.

Frequently asked questions about tulips and pets

Are tulip leaves also toxic?

Yes, tulip leaves are also toxic. Although the concentration of tulipalin A and B is lower than in the bulb, it is enough to make your cat or dog sick.

How much tulip is dangerous for a cat?

How much tulip is dangerous for a cat depends primarily on your cat's weight, which part of the plant was eaten, and how much. There is no safe threshold we can provide. Our advice is primarily to keep tulips as far away from your pets as possible, unless the animals do not have a naturally curious character.

What if my dog has dug up a tulip bulb?

A dug-up bulb is the most dangerous scenario because the bulb contains the highest concentration of toxic substances. If your dog has dug up a tulip bulb, call your veterinarian immediately, even if your dog only chewed on the bulb for a moment.

Are all tulip varieties equally toxic?

Yes, tulipalin A and B are present in all types of tulips, regardless of color or type. Whether it is a botanical tulip, a parrot tulip, or a classic red tulip. It makes no difference to your cat or dog. The toxicity is in the plant, not the variety.

Can cats get sick from the water in a tulip vase?

That is possible. The toxic substances leach into the vase water, which means that water can also be harmful to cats. Cats that are used to drinking from standing water are therefore also at risk without even touching the plant itself.
