Is it normal for a cat to become more vocal with age? My girl has always been a talker but she's pushing 13 and is more vocal than ever and seems to have lots of energy when I get home from work and throughout the night. She also meows loudly each time I pet her and purrs loudly while meowing. I will admit to spoiling her as a kitten by turning on the bathroom sink water for her to play and drink in. Now it'll be 3-4am and she'll start howling for attention/sink play and flying all around the house. Last check up showed her in good health albeit overweight but I was just not sure if this is a common thing or if she is in fact trying to plot my murder.
