The short answer: Yes, but only in moderation.
The long answer: Lima beans are soft, starchy, green-coloured beans that are a member of the legume family. The seeds are also called by many different names: butter beans, chad beans, double beans, Madagascar beans, sieva beans, and wax beans. They contain fiber, protein, iron, and potassium—nutrients that your cat does not need but can ingest in small amounts.
Lima beans need to be cooked properly before being fed to your cat. This is because of the poisonous compound linamarin as well as other harmful bacteria that may be found on the coating of the raw seeds.
Canned lima beans cannot be given to your cat since the water is high in sodium and contains preservatives that can affect your cat.
How to feed lima beans to your cat: Rinse and soak the lima beans. Aside from reducing cooking time, soaking will make them easier to digest. Do not add salt, sugar, garlic, onion, and other seasonings to the boiling water since these ingredients may cause health complications. Boil until the lima beans become soft enough to chew. You can serve them as whole seeds or mash them.
In summary: Consult with your veterinarian before feeding your cat lima beans. She may have pre-existing health issues that may be triggered by eating lima beans. When consuming lima beans for the first time, your cat should be monitored closely for 24 hours for any changes in her mood, behaviour, and litter box habits.
