This is something my sister used for her cat. The rubber inside is damaged, but it can still be used. The camera also works. (You might be able to purchase a replacement by contacting the manufacturer.) I bought the dishes from the manufacturer, so I have two. The main unit has some yellowing. There are no instructions, so please refer to the internet. It has a camera! There is still a slight smell of pet food, but it has been washed, so I personally find it acceptable. Please understand that this is a used item.
