This is Max the Cat. He usually scared of Fluffy the Bird, but still, always so curious and interested in her. Interested in.....as a playmate, not as food, I presume.
Fluffy is the strongest, I mean stronger than Max and Nicky, the older cat. She won't flinch if they get near, and if they are too close she is ready to bite, not backing off. Don't say Fluffy is an aggressive bird, she is not. She trusts Nicky, and Nicky leaves her alone, so they have peace to each other. But Max, he is just a baby, so too curious and want to touch Fluffy, sniff Fluffy, follow and chase Fluffy, but it looks like he just want to play with her, to stay close to her. Fluffy doesn't trust this kid, so Max look so sad when Fluffy doesn't let Max come closer.
This photo is a rare occasion and both seems OK, looks like he is whispering a secret to Fluffy's ear! The upper photo looks like Max is ready to lick her clean!
