I have one very friendly cat named Clemson who just needs to be fed twice a day and his litter box changed 3 or 4 times while I am gone. I also have a large (about 100 lbs) Bernese Mountain Dog named Cornwallis. He is extremely affectionate and friendly to strangers, he just needs to go on a short walk (down the block) once a day and let out three times to use the bathroom. He also gets fed twice a day.
