Japanese cat cafés feature strict rules to ensure cleanliness and animal welfare, in particular seeking to ensure that the cats are not disturbed by excessive and unwanted attention, such as by young children or when sleeping. Many cat cafés also seek to raise awareness of cat welfare issues, such as abandoned and stray cats and many often have cats from local animal shelters to help them lose any fear of humans and advertise them for possible adoption. From 2012 the cats could be displayed until 8 pm, but in 2016 the guidelines of the environment ministry state that they may visit and play with customers until 10 pm.[10]
