Ever since I brought 2 kittens home my older cat lost his voice why?

Hi, zibaa1!

Just like us, cats have emotions and react in certain ways to show those emotions. You're older cat might be feeling a certain way because of there being newer cats in the home. Do the kittens and your cat get along with each other, please?

My cat meows a lot to get attention from me. When I used to have another cat in addition to him, he hardly ever meowed. I also think that part of the reason that he meows a lot is because he's lonely. I've been thinking about getting a kitten to keep him company...

Thanks!

Lost his voice? What do you mean? Is he not talking? Or does he sound different when he talks?

Thanks for replay
There are 3 reason he may have lost his voice

a- new kitten and new allergies or germs from them
b-respiratory infection
c- hypothyroidism
They are getting along now

Hi hheath541
My older cat voice is changes. He does not meao in regular sharp voice. This happened right after I got 2 new kitten.so I am thinking may be it is due to
New kitten, or he is depress
