Rupert is a symphony of sounds. When I come home from work I am treated to his full repertoire of resonance! I call them his baby gorilla noises, he chirps, gargles, yodels, yips, arrooooos and then for his encore it's usually a few sneezes.
Jemma hardly ever makes a sound and when she makes her sharp yip followed by a yodel I practically jump out of my skin from being startled!
I guess they balance each other out
