Bio-insecticides, which are derived from natural sources such as plants or microorganisms, are generally considered to be less harmful to cats compared to synthetic chemical insecticides. However, it is still important to use bio-insecticides with caution around cats, as some natural compounds can still be toxic to them if ingested or if they come into contact with their skin. It is always best to follow the instructions on the bio-insecticide label and to keep cats away from treated areas until the product has dried or settled. If a cat shows any signs of illness after being exposed to a bio-insecticide, it is important to seek veterinary care immediately. **
