They are professional climbers

Well, cats are professional climbers and love to spend their time looking for new adventures, such as hiking your counters and drapes. That being said, you have to provide them with a safe environment and try to prevent them from getting hurt. To be more specific, try to move small or fragile items that could injure them when climbing. Nonetheless, you should opt for a cat condo or tree, so that your feline can be comfortable and safe. 

“They love to be on top of things and up high surveying down, where they feel most safe and comfortable,” says Borns-Weil. “They’re not trying to be naughty. That’s just where they’re comfortable.”
