Animals are a lot like humans for when we are happy our immunity is strong and love and life force races through our veins. When we are depressed our immunity runs low and we can easily get sick. Many pet parents are very careful about feeding the right food, providing plenty of exercise and buying the right toys and treats. Not that those things aren’t important too, for they are, but the best thing you can do for us is to make yourself happy because when you are happy then we are happy too.
