If you have a swimming pool and let your cat outside, be careful. You don’t want your cat to fall in the swimming pool and drown. To prevent this, consider getting your cat used to the water. That way if it falls in, it won’t panic and will likely survive.
The key is to get your cat in the water as often as possible until it’s comfortable swimming on its own. This can take time but if you’re consistent, your cat will gradually lose its fear of water and learn that it can survive. That will give you one less worry the next time you let your cat out near your swimming pool or any body of water.
