A video of cats interacting with water could show a variety of different things, depending on the context and the individual cats in the video. Some common themes might include cats drinking from a bowl or faucet, cats playing in or around a pool or other body of water, cats getting a bath or being groomed with water, or cats getting wet in some other way (such as from being caught in the rain or jumping into a puddle). The cats' reactions to the water could also vary widely, from seeming to enjoy it and playing in it happily, to appearing uncomfortable or scared and trying to avoid it.
