Why is my aggressive cat suddenly affectionate and meowing more?

I am sorry to hear about Lucy! Many cats can have personality changes at around 2 years of age as they truly reach maturity. That compounded with the fact that she is unspayed and has had a changing life situation over the past few months could definitely be affecting her personality. I would recommend an exam by a vet and having her spayed. I would recommend a feline pheromone diffuser in the house called Feliway, and a calming supplement such as Composure or Zylkene https://m.petco.com/shop/en/petcostore/product/vetri-science-composure-feline-bite-sized-chews# as well. If her aggression continues then a veterinary behaviorist consultation would be recommended.

There are two very common health issues in older cats that are known for causing a sudden increase in appetite like this: hyperthyroidism, and diabetes. I would definitely recommend taking Lucy to the vet for a check-up when you are able to - he/she can do blood work to check for these problems. If she does have one of these illnesses, they are normally very treatable with medication once a diagnosis is made :)

These sudden changes in temperament and the weight loss are commonly due to an endocrine problem called hyperthyroidism. The thyroid starts working more than normal increasing the metabolism (that is the cause of the weight loss) and causing behavioural changes similar to what you described. A clinical examination at your local veterinarian is essential to confirm this clinical suspicion and treat appropriately. A blood test and urine analysis are needed.

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!

Sudden changes in behavior can indicate that Mulan does not feel good or that she is stressed. Monitor her VERY closely for any signs of illness. Monitor everything. Have her examined if there are concerns Mulan is not feeling well. https://www.petcoach.co/article/10-signs-your-cat-is-stressed/ If you suspect stress, please check back in.

As with any sudden behavioral change, an exam to rule out any health issues is always the best first option. If the weather is changing rapidly and you are seeing her seek out warmer spots such as blankets, by heater vents, etc that could also be related to the behavior. Adding a warm blanket out of the dryer to her bed, or providing a place for her to sleep near a heater may help. However, if you are concerned enough about the change, a vet exam for a bit of peace of mind is always good.

Hi, I hope Bonnie and Scarlet are doing well. heat cycles can cause some abnormal behavior in cats, so this may be it. As long as they are eating and drinking and using the litter box well, I don't see a medical emergency. Bedbugs can move to animals but usually don't cause a problem. I would examine them both for signs of bugs or red spots and treat with a medication called revolution you can get from your vet. The weather may be another factor. If it is unusually warm out, they may be just laying around and not very active. I would monitor them both carefully for signs of not eating or not using the litter box properly and if you do see that, take them to a vet. Good luck, I hope this helps!
