Money trees (Pachira aquatica) are non-toxic to cats. According to the ASPCA and multiple pet safety sources, they do not contain poisonous substances harmful to cats. However, if cats eat large amounts of the plant, it can cause mild gastrointestinal upset like vomiting, diarrhea, or nausea. Thus, while occasional nibbling is unlikely to cause serious harm, it is still best to discourage cats from chewing on these plants to avoid any digestive issues or damage to the plant.
