Sometimes when I'm doing some work on an evening my kitten goes a bit nutty. He jumps onto the sofa so he's at eye level with me, then when I look back at him he does his chirrup sound and BOLTS upstairs...repeat as many times until bedtime. Am I scaring him? Does he want something?? He's a very loving kitten and always sleeps in my bed with me... but I'm aware I'm out the house for time periods at a time :(
