I found an article that I think might be helpful for all of us. This is the time of year when people are trying out those new gifts. Right now, aromatherapy and essential oils are very popular. I think it is imperative that we know that some essential oils including aerosolized oils can be toxic to pets. This link is specific to dogs and cats but I feel certain that squirrels could also be affected.
