What is Carrageenan?
Carrageenan is a thickener.
It’s mainly used in wet cat foods (usually gravy based). You won’t usually find carrageenan in dry cat food, because it’s a thickener.
Carrageenan is made from red seaweed products (also called Irish Moss). Whilst it’s technically ‘natural’, it’s still linked with harm.
Carrageenan in Cat Food
Carrageenan is found in many wet cat foods.
The reason is to thicken cat food for a desirable texture. Gravy and pate based cat foods tend to use carrageenan more often.
Some brands tend to use carrageenan more often than others. For example, Blue Buffalo use carrageenan a lot, whilst Hill’s Science Diet don’t seem to use it.
Why Is Carrageenan Bad for Cats?
Degraded carrageenan may cause inflammatory conditions including:
- Colitis
- Arthritis
- Irritable bowel disease
- Colon cancer
Some carrageenan degrades with digestion. Degraded carrageenan is used to test models of inflammation.
The amount of carrageenan used to cause digestive disorders is much higher than found in cat food (less than 1%). Carrageenan is generally regarded as safe (GRAS) by the FDA.
Tolerance studies exist for rats and dogs, but none for cats. A safety panel suggest 750mg/kg wet feed is safe for cats (extrapolated from dog safety research).
Problem?
You won’t get information on how much carrageenan is in your cat food. Although it’s likely very small, the grey area is a problem.
How to Identify Carrageenan in Cat Food?
Here’s how to find out if carrageenan is in your cat food.
Check the Ingredients List
By law, cat food has to include an ingredients list. It’s usually on the back or side.
As carrageenan is a minor ingredient, it will usually be down the list so check carefully.
Check Ingredients Online
Buying online?
Some retailers don’t put out ingredients list, but others do.
Hit control + F (command + F for mac users) to see if there’s any carrageenan in your chosen food. Make sure you get the spelling right.
Here’s an example on Chewy:
Check Other Names for Carrageenan in Cat Food
Some countries use numbers for additives, including carrageenan. In Australia, for instance, carrageenan is E407.
Words like ‘gelling agents’ or ‘stabilizer’ can include gums and carrageenan. If you see these terms, it’s best to stay on the safe side.
Here’s a longer list of names for carrageenan to watch for:
- E407
- Irish moss
- Algin
- Seaweed extract
- Polysaccharide
- Red seaweed extract
- Carrageenan gum
- Chondrus
- Carrageenin
- Thickeners
- Gelling agents
- Vegetable gum

How to Find the Best Cat Food Without Carrageenan?
Make sure you choose cat food that meets your cats dietary needs. Check for a statement of nutritional adequacy on the label.
This shows your cat food meets AAFCO’s nutrition guidelines for:
- Growth: Kittens (up to 1 years)
- Maintenance: Adult cats (1-7 years)
- All life stages: Kittens or adults
- Supplemental: Occasional feeding only (not complete)
AAFCO don’t set nutrition guidelines for senior cats. Find guidelines at American Association of Feline Practitioners (AAFP) website.
Most cat foods suitable for all life stages are better choices for older cats.
Choose High Protein Cat Food
Protein is the most important nutrient for cats and their preferred food source as carnivores.
The nutrient is high in animal foods like chicken, fish, turkey, and beef. You’ll want to make sure you choose foods high in these ingredients.
Grain-based protein (e.g. wheat gluten) is lower quality. This type of protein has fewer essential amino acids, which are what cats need to use to fuel muscle strength.
As a general rule, aim for 40% protein on a dry basis. Use a calculator to check.
