"! He also LOVES my bunny and plays with him and used to be best friends with our weero and canary.  

 He does know the difference though and any ""wild"" bird that used to fly at our window at our canary used to set him off and he would meow angrily and body slam the windows. He also gets angry at any cats he sees outside and also body slams the windows at them and does this horrible growl when hes getting shitty cos he can hear them! It really sounds evil when he growls and he has 2 types, his angry growl and his excited/playful growl which sounds like ""whirrrrrrrr"". He also i believe if he got out to other cats would kill them as he puffs himself right up into pure muscle and his tail gets like a bottle brush cos of how angry he gets when he sees or hears them outside"
