When I started out, I used to maintain a wait list. I took $50 deposits for people to get on the wait list and when kittens were born I used to go down the list so people could pick their kitten and move forward from there.
I stopped doing that really quickly for several reasons. First and foremost, people were hoping for specific genders and colors. I can usually predict what colors and patterns we might get but there is never a guarantee. So when people are on my wait list and I don't get the color/pattern they are waiting for then they either go somewhere else or they want first pick up upcoming litters that may not have what they seek either. And that was becoming a mess, so that was my main reason not to maintain a wait list anymore.
Then people were on the list in the order that I received the $50 deposits. It happens so often that the people in 4th place were ready to pick while the people before them wanted to wait until the kittens were 8 weeks old. This caused a lot of irritation and impatience with waiting families which was also a good reason not to have a wait list anymore.
And then there were the people that paid a deposit, were too impatient to wait and went somewhere else without telling me. I tried to contact them because it was their turn to pick and I would not hear anything back at all, while other were in line waiting to pick their kittens. So for all those reasons I stopped maintaining a wait list because it was a stressful mess.
I work on a first come first serve basis because people often say something different than they do. I have had it happen numerous times that people said they would commit to a kitten, send a deposit and the deposit would never arrive. All the while I would be holding a kitten that I could have sold 5 times already for someone who said they'd send a deposit and never did.
When I emailed you with what I have available, it means I have those kittens available at that specific moment that I send the email. It may very well be that by the time you email me back, the kittens I had available are sold. I currently have 5 available kittens and 23 applications. I don't hold kittens without either a deposit via Paypal or a tracking number for the check/money order. Once I start going through applications, kittens are usually sold very quickly.
I am very sorry if that is the reason you're missing out on kittens from a specific litter. I get far more kitten requests than I have kittens available, which is why I choose to do this method as it simply works best for me. I will be happy to refer you to breeder friends who have kittens or tell you about the upcoming plans to help you find the kitten you want.
