Our new kitty wheezes and meows like a creaking door... is this abnormal?

If Kitty is wheezing,the poor baby could have bronchail asthama, lungworms, upper respiratory infection, I could name more but, I think even though you just had kitty to the vet, I would take her back & have them give her another look and tell them your concerns. Make a list of questions so when you go, you don't forget anything you want to ask. Tell them about her meow and her breathing, any and every little concern you have. Remember, Kitty counts on you don't wait 'til it's to late.
