Hi, my 4 month old kitten recently has seemed odd. Last night she was like blowing her nose (not with a tissue obviously) and her nose was wet and she was breathing really loud when asleep. This morning she woke up and was making a throwing up sound. She didn't throw up though. Now also recently when she enters the bathroom to use the litter box she like meows I don't know if shes constipated because she doesn't even step in the box she just goes near it and is meowing. She is very hyper and eating well. Also every time after she eats her stomach makes a humph sound. Should I see the vet or Am I just being paranoid?
