High-Pitched Meows

My cat is currently about 8-9 years old and he's a normal Blue Russian. He usually has normal meows and meows if he wants attention or food or if something's bothering him. However, for the past about 3 days, his normal meows have been very high-pitched. He meows at times like usual and his behavior hasn't changed as far as I can tell. His normal meows are just really high-pitched. I would love to take him to the vet but since I live with my father, he has final say, and he doesn't want to pay for it because he thinks it's nothing. I am still worried though so can anyone tell me why he's suddenly doing this? Is it something I need to be concerned about? Should I force my dad to take him to the vet? Or is it normal and maybe it'll go away? Thank you for your time~

Hello, a change in the pitch of a cat's meow can indeed be an indicator of ill health. Respiratory issuses, signs of distress or pain. It could even just be a sign that he is loosing his hearing slightly. However when this happened to my cat we noticed her meowing gradually become louder over the years. It wast overnight. i would suggest persuading your dad to allow you to take kitty cat to the vet. Would you be able to persuade him if you could show him some info online?

That's what I'm afraid of.. gradually could just be age but this did happen over night. As for the information online, I'm not sure it would help but it wouldn't hurt to have it. Do you have some online information?

I'm still learning how to use the site! But I will do my best to pop something on! May have to give me time to work it out though, my phone does not like this site!

Oh absolutely, take your time. But thank you so much for your help!!
