If your cat's voice is hoarse but it's otherwise energetic, consider whether it's drinking too little water, which could be causing it to become dehydrated or have other health issues. If you regularly feed your cat too much meat, or if its kibble is too dry, and it's not drinking enough water, it's very likely to develop these problems.



Secondly, consider whether it is caused by a respiratory problem in the cat. If the cat has underlying conditions such as feline herpesvirus, calicivirus infection, or a common upper respiratory tract infection, the cat's tonsils or throat may become inflamed, resulting in a hoarse voice.

In addition, a cat's hoarse voice can also be caused by persistent meowing. For example, when a kitten enters an unfamiliar environment, it will usually howl continuously, and after a long period of continuous howling, its voice will become hoarse. If you are unsure of the cause of your cat's hoarse voice, it is best to take your cat to the vet for further diagnosis as soon as possible.
