It does all sound normal. My Syrian boy Raffy won’t come out when I want him to! He’s up about 9.30pm but spends AGES sitting in a private little corner, having a very good wash. If I offer him his tube to come out he sort of looks like “you’re interrupting me “. And ignores it. Sometimes he’ll come over and contemplate the tube - but then turns round and goes back to his wash corner.
So he keeps me waiting! Then when I am ready to go to bed he pesters to come out!
