Even with domestication, cats possess a strong instinct to stay in vertical perching spots so they could have a good view on what is happening in their immediate environment. This is an instinct of self-preservation that they have inherited from their wild ancestors. In the wild, staying on top of trees makes it possible to see potential threats and give an alarm to the other cats. There should be enough vertical spaces in your home for your kitty or he will creating his own. He might knock down expensive figurines, potted plants, books, etc. in an effort to find a good vantage point.
Cats living in a multi-pet household will also benefit from having vertical spaces to go to when they are overwhelmed by anything that’s going on in the house. Cat trees and kitty condos also meet your pet’s needs for vertical spaces, so are window perches.
Sudden changes in your pet’s health and/or behavior should warrant an appointment with your best veterinary clinic Plano, TX sooner rather than later.
