Filou and Tigris eat spiders
They cannot catch birds because they have a netting around the balcony
But they met a DAWG- my mom's dachshund Amber. Filou wnet there curiously and even came very close to a nosekissie

Tigris went under the bed. An hour later or so, Amber was feeling a little more secure and wandered around to see where the other furries were. She met Tigris under the bed and - yawl- got a scratch on her nose

So I would say my boys are territorial with dogs
