Many people still get confused about what an emotional support animal is. Well, if you are also a bit confused, don’t worry, I will simplify it for you. Emotional support animals are your furry companions that help you deal with mental illness. There are a lot of benefits to having emotional support animals. And you can also live and fly with your pets without paying any extra charge if they are ESAs. You would need an ESA letter signed by a licensed mental health professional. This letter proves that you suffer from a mental or emotional illness that requires your pet to be with you.
