Here's why:
* Seaweed isn't a common pet food. While some animals, like sea turtles, eat seaweed, it's not a staple food for most pets.
* Specific types are needed. Not all seaweed is safe for pets, and the type you'd need for a pet depends on the animal.
* Quality control: Pet stores are more likely to stock food that's been specifically tested and formulated for pets.
However, there are some exceptions:
* Aquarium stores: Some aquarium stores carry seaweed as food for herbivorous fish.
* Specialty stores: You might find seaweed products at stores specializing in reptiles or exotic pets.
* Online retailers: Websites that sell pet food and supplies may carry seaweed.
If you're considering giving your pet seaweed, it's important to consult with a veterinarian. They can advise on the appropriate type, amount, and whether it's safe for your pet's specific needs.
