Why is my quiet cat suddenly meowing constantly and acting disturbed?

Thank you for submitting your question regarding your cat. I would recommend a trip to the veterinarian to ensure she is not suffering a medical problem causing this behavior change. A disease known as hyperthyroidism can cause increased vocalizations in a cat. It is usually accompanied an increase in thirst and urination, hyperactivity, possibly vomiting/ diarrhea and weight loss. She will likely have blood work performed to rule out this as well as other internal diseases. If she is found to be healthy, then you can discuss behavioral modifications at home. I hope this information helps!

I would get Snowy spayed. The reason why she wants out of the house so much is that she wants to mate with male cats. The only way to stop this behavior is to have her spayed, so I would speak with a vet about having this done as soon as possible.

This is a common behavior in intact females (not spayed). The fact that it has become more frequent makes me wonder if anything has changed with her hormonally like an ovarian tumor. I would have your vet take a look at her when you can to ensure everything looks ok. You can also have her spayed to stop these episodes. I hope this helps!

I recommend to video tape the behavior and then have Snow Minue examined by the veterinarian. This could be related to pain or breeding behavior. If Snow Minue has not been spayed or neutered, this needs to be done. Also, he needs vaccinations because he is not protected against basic diseases. Since he can't talk and tell you if he is in pain or has any problems, he needs to be examined. Show the doctor the video and make sure to keep him indoors. I hope this helps.

Thank you for submitting your question regarding Mino. I do recommend that she sees her veterinarian if her behavior persists. Depending on when her last heat cycle was, she could be experiencing a false pregnancy. If not, there are metabolic conditions such as a thyroid disorder that can cause increased vocalizations in cats. She could also be experiencing pain somewhere. Her veterinarian will perform a thorough examination and based on these results guide you on if diagnostics or treatment are needed. I hope this information helps!

It is possible something startled Meesho. Moving him to a calm, quiet room with food, water, litter, etc may help him to relax. If he seems in a lot of distress, is trying to go potty and can't, or has signs of illness (vomiting, pain, not eating, etc) this could indicate he is very ill and should be seen by a vet right away.

Certainly personalities can change as cats get older, but i would recommend making sure there isn't a medical explanation for her behavior. We see conditions like hyperthyroidism (a high thyroid level) which can cause increased activity as one of its first signs. If her exam and bloodwork is all normal, it might just be a behavioral change as Princess gets older and is nothing to worry about. I hope that was helpful.
