I've stayed overnight at a family friend's house before in order to care for her two dogs. I took them for walks and made sure they were well fed. I've also stayed overnight to cat sit for a friend. I made sure his litterbox was taken care of and that he had fresh food and water. Occasionally I'd bring over special treats for him. Id addition to caring for these pets, I'd also tend to housework if anything needed to be done. I love animals and enjoy spending time with them.
