We changed names on our cats. I don't remember what the name was for our first female burmese cat was but we changed it to Poona.
And then our last black cat we got from SPCA we changed to Suki.

I personally think its the way you call to your pet.

Our female dog has this huge long name and we shortened to short names and she comes too all.
But if are angry or upset our voices tell her and she won't come as she knows she is in trouble. so, its all in the voice you do when you call their name.

You can change to any name you want too that you are comfortable with.

Just make sure they don't rhyme with other pets names as we have had to watch that.
