Heidy definatly does know her name, but really responds to "Dee Dee" or "Deeee" as thats what I mostly call her, if I do call her Heidy usually its when she isnt paying attention or is being naughty, and then she she is where I wanna her to be quick as a flash, lol.
Monty knows his name and will pretty much always come to you, or if not will prick his ears toward you and look at you, its sooo very cute. I think he thinks he is the royal man of the house, lol. He proved he really does though once, as when we lost him and the people who found him, found out his name from the posters, they said he had a look on his face of a mixture like "Uh oh, I am gonna be in soo much trouble" and "how'd you know?.
Ozkar kinda knows his name, but responds more to Ozzy, but since they sound the same I can't really tell, however, being the very talkative cat, he always answers with a meow.
Sable knows her name, but tends to ignore me alot now, since she is grown up and there is too much fun to be had to pay attention to mummy! lol. Sometimes she will come if she is really sooky, or if its dinner time, and others she will aknowledge you with a prick of the ears.
Lukas knows his name & will answer with a meow when called & comes, also, to a whislte-a childhood friend's mom taught all her cats to come to a whislte & I've done it with mine-gets looks from "cats can't be trained" people"
I know Simon knows his name definitely, Sapphire I'm pretty sure knows it but does not respond
and I think Antigone and Pandora are finally figuring out their names. Also Simon responds to kitty kitty kitty like nothing I've ever seen before, its like he can't resist it! he will come running from anywhere no matter what he's doing if I kitty kitty call him
They also respond to various nicknames, mostly Baby (Katie), Little Bug (Gracie), Hunk (Peter), Clee-Clee (Claire). Of course, this only when the feel like it!
LuckyGirl will come if you call her, or if your in the same room she'll just look at you like "can't you see I'm comfy?!" But she will also come up on your lap if you pat your leg she'll jump right up. She also comes running if you blow kisses or make a smooching sound. Even if I'm just kissing hubby goodbye she comes running. Or if you shake her treats dispenser... she's always looking for a handout!
Trout knows her name but she will ignore us on purpose if we call her..Unless I shake her treat bag. Her dad will be holding her and she'll be looking away, and he will say "Trout, Trout, TROUT!!" and she still would rather look away than look at him
When I come home from work she is excited though..I will say "where's mommies furry sweety?" and she will come running
Carly is just learning her name and is at the same point as Much - acknowledging you called, coming sometimes. Lucy knows her name so well that she will perk up when we're using it in normal conversation. Still doesn't mean she always comes.
