French marigolds (Tagetes patula) are toxic to guinea pigs. They contain a compound called pyrethrin, which can cause gastrointestinal upset, liver damage, and even death in guinea pigs.
Here are some safe alternatives for guinea pigs:
* Timothy hay: This is the staple of a guinea pig's diet.
* Fresh vegetables: Offer a variety of safe vegetables in moderation.
* Guinea pig pellets: Choose a high-quality pellet specifically formulated for guinea pigs.
* Fresh herbs: Some safe herbs for guinea pigs include cilantro, dill, and parsley.
Always consult with your veterinarian before feeding your guinea pig any new food, including herbs.
