I have three different....
I have three different breeds.....beige/violet, mosaic (or white ebony), and standard.
My Mosaic (girl - almost 2 years old) has a VERY particular attitude and you have to take extra care with her....let her do things at her own pace, or she will bite. BUT.....when out for play time, I can say...."Tuya, come give Mommy a kissey," and she will hop right up into my lap and reach up and give me a kiss!!! It is the SWEETEST thing EVER. But.....she does not want anyone to reach into her cage or even reach down and pick up her up during playtime. She will bite and bite HARD if you are not extra calm and extra gentle with her...and you have to sneak up on her to get her. When I pick her up from playtime to take her back to her cage, she violently shakes her head "no," over and over again! I have thought many times about sending a video to the funniest animal video show - LOL!!! And, she will bite when I am cleaning up the fallen hay from her cage...if I make too much noise. Repetitive sounds aggravate her. If you tap your hand repeatedly on your leg, floor, etc., she will eventully viciously attack it!!!
My Standard (girl - approx. 5 years old). I rescued her from a person trying to sell her for $50 on Craigslist!!! I ended up getting her for free, after I wrote about 300 e-mails!!! She looked VERY rough when I got her...even though she was a nice weight. But....she was being fed CHARLIE CHINCHILLA - NOOOOOOOOO!!!!! In any case, she seems to be very sweet, but does not really want much interaction with us yet. This could just be because of her past circumstances??? Time will tell.
My Beige/Violet (boy - 2 years) is the most LOVABLE, cuddly, beautiful thing I have ever experienced!!! This could have something to do with the fact that he a boy, but I am not sure. Neither of my girls have EVER urinated on anyone....even though I have heard a lot of stories about this. Sometimes he will play around and try to hide from me, but 99.9% of the time, I can just call him and he hops right up to the cage door where I am. I can pick him up and cuddle him anytime - 24-hours a day. He is VERY smart, and will bang his dish repeatedly on the wood shelf if he runs out of pellets. If his water bottle happens to clog or get low, he will hop around his cage making a LOT of noise until I take care of it. He does have red eyes (which I though was scary looking at first), but he is one of the BEST things that ever came into my life! He hops all over me...mostly my head....during play time. He is a very social chinchilla. He has NEVER bitten anyone at all....EVER....not even gently. AND, his fur is by far softer and denser than the other two chins.
Oh....also, each chinchilla is in their own separate cage and are not being bred, however, the Beige/Violet and the Mosaic are with pedigree. Both pedigrees were born on the small side, so I do not think they are ready for showing....need to fatten up a little more. I am getting ready to begin mixing either PANR or Manna Pro in with their current 100% Oxbow feed/hay diet.
I believe how a chinchilla turns out depends more on how YOU treat and care for your chinchilla and how much time you spend with him or her. Even though I voted here, I am not sure this poll is going to help you determine a specific color that has a history of exceptionally good disposition.
Thanks for the interesting topic/poll though. : )
