Quick answer: No, cats shouldn’t eat Twiglets, but one or two stolen pieces are very unlikely to cause harm. Twiglets aren’t toxic; the problem is salt. They’re a salty wholewheat snack coated in yeast extract, with no nutritional upside for cats. If your cat ate a whole bag or seems unwell, call your vet.
| Twiglets ingredient | Concern for cats |
|---|---|
| Wholewheat flour (the bulk of the snack) | Not toxic; just carbs cats don’t need |
| Yeast extract flavoring (Marmite-style) | Not toxic, but very salty |
| Added salt | The main concern |
| Vegetable oils | Extra fat; can upset stomachs |
| White pepper | Mild irritant in larger amounts |
Ingredients are based on the standard Jacob’s Twiglets pack. The original recipe doesn’t list onion or garlic, but flavors and recipes can change, so check the pack your cat got into.
Are Twiglets Toxic to Cats?
No. Nothing in standard Twiglets is poisonous to cats. They’re still a poor snack for them for three reasons:
- Salt: Twiglets carry around 2.8 g of salt per 100 g, so a 45 g bag holds over 1 g of salt. Cats are small, and salty snacks can cause vomiting, diarrhea and heavy thirst. Large amounts can lead to salt poisoning.
- No nutrition cats need: cats are obligate carnivores. A wheat snack gives them carbs and calories, not the animal protein and nutrients they rely on.
- Hard, sharp texture: the knobbly sticks can scrape the mouth or cause gagging if swallowed in big pieces.
What About the Yeast Extract?
Yeast extract (the same idea as Marmite) isn’t toxic to cats, and small amounts are even used as a flavor in some pet foods. The issue is the salt it’s paired with. Cats with kidney disease or heart problems are more sensitive to salt, so keep salty snacks well away from them.
My Cat Ate Twiglets: What to Do
- Check how many are missing and whether it was a flavored variety.
- A few pieces: make sure fresh water is available and watch for vomiting, diarrhea or unusual thirst over the next 24 hours.
- A whole bag, or your cat has kidney or heart disease: call your vet.
- Go to a vet right away for repeated vomiting, wobbliness, tremors, extreme thirst or lethargy, which can be signs of salt poisoning.
- Don’t make your cat vomit at home, and never use salt to do it.
- Poison lines: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661 (fees may apply).
Why Does My Cat Want Twiglets?
Yeast extract has a strong savory, meaty smell, which is exactly what grabs a cat’s attention. That’s also why it’s used in small amounts in some cat foods. A meat-based cat treat gives your cat the savory hit without the salt.
Safer Savory Treats
- Plain cooked chicken or turkey, no skin or seasoning
- A flake of plain cooked white fish
- Freeze-dried single-ingredient meat treats
- Commercial cat treats, which are formulated with cats’ sodium needs in mind
Other salty snacks to keep away from cats include pretzels, prawn crackers and seasoned crackers. For the full picture, see our cat food safety guide.
Frequently Asked Questions
Can cats eat Marmite?
Marmite isn’t toxic, but it’s very salty. A lick won’t hurt a healthy cat; don’t make a habit of it.
Do Twiglets contain onion or garlic?
The standard Jacob’s Twiglets ingredients don’t list onion or garlic. If your cat ate a limited-edition or flavored version, check the label, since onion and garlic are toxic to cats.
How many Twiglets are dangerous for a cat?
There’s no exact number, but a few pieces are very unlikely to cause problems in a healthy adult cat. A large share of a bag is worth a call to your vet, especially for small, young, elderly or kidney-compromised cats.
Can kittens eat Twiglets?
No. Kittens are small and more sensitive to salt, and they need complete kitten food for growth.
