I currently have exactly the same situation, but with just 1 chick and my cat. He is remarkably restrained about trying to eat him! But does like to sit and watch, especially when the chick is running about on the floor.
If anybody happens to have a chick going spare in North Fife, I will gladly take it. Mine is very lonely and constantly demands attention. He/she is 5 days old and is sooooo noisy!
