How do I get my cat to drink more water in hot weather?

Add a second water station away from the first, since a cat who won’t walk across a warm apartment for water may still drink from a bowl in a different room. Wet food is the biggest lever: a canned meal can contain up to 80% water, so shifting even one meal a day from dry to wet does more than almost any bowl trick. Ice cubes in the bowl, a shaded fountain away from a sunny window and fresher water changed more than once a day round out the approach. Skip anything that adds sugar or dairy to make water more tempting.
