Stink bugs are not poisonous to cats. However, their defensive secretions can cause temporary irritation and discomfort, such as drooling, vomiting, mouth and eye irritation, and digestive upset if a cat eats or plays with them. While these symptoms are usually mild and temporary, eating a large number of stink bugs can potentially cause more serious issues like digestive blockage that may require veterinary care. Additionally, if the stink bugs have been exposed to pesticides, there could be additional risks for cats. Overall, stink bugs are not toxic, but their smell and secretions can irritate cats and lead to mild health issues.
