I have many animals myself and my motto is you can never have too many. I have a couple cats and a 4 month old puppy. I am 18 but I have been taking care of pets since I was about 10 years old. I have an unfenced yard but I have multiple leashes and leads so that animals get plenty of outside and exercise time. I feed animals 2-3 times a day depending on what the owner would like and I keep multiple water bowls full at all times. I have a water bowl raised up for bigger dogs and couple ones on the ground for smaller dogs. I have a cat tree for the cats and I have an extra room I’ll get toys out and let them play in with just other cats. I also keep the windows up so they can lay in the window and get sun.
