Many of us consider our dogs and cats extended members of our family. While we know to keep dangerous things like chocolates and certain plants away from them, there are some other common household items to be aware of, according to the ASPCA. Take extra care to keep wine away from animals -- it can cause illness and even coma. Don't leave burning candles unattended: Kittens are attracted to the flickering flames. And if you have a dog that makes a habit of drinking out of the toilet, use non-toxic cleaning products in the bathroom.
