Whether you park your car in the garage, in the driveway or on the street, you need to be vigilant for the hazard of fluids that can leak from the engine. Antifreeze is especially attractive to animals because of its sweet taste, but it can cause poisoning. Also watch for leaks of motor oil, transmission fluid, power steering fluid, and other fluids such as differential and brake fluid. Your mechanic can tell you what colors various fluids are and how to soak them up. One remedy is to pour cat litter over the site of the leak. The cat litter will absorb many fluids and, once absorbed, can be swept up and disposed of.
