animal sounds

We are at Grammy and Papa's house. Bedtime has been a little more challenging because it is very exciting here. Anyways, Quint was in bed working on falling asleep and I was in rocking Russell. Then out of nowhere I heard a sound, it was a cross between a bird sound and a growl:) What was it? I could not tell if it came from Quint or outside. When I heard it the second time I was pretty confident it was from Quint. As I continued to rock Russell, I thought to myself I guess we can cross animal sounds off Quint's "need to learn" list.
