Kitten enquiries

I am so tired of emails from people who have no intention of having a kitten from us!!!!
I am also sick to the back teeth of those who email me about each litter- they obviously don't expect me to remember their email address from previous enquiries.
Is this the computer age version of window shopping?
I would have thought that there were enough web sites out there to satisfy their cravings for kitten pictures, without the need to waste my time making enquiries about kittens they have no intention of buying.
The fastest way to see if they are serious or not seems to be to suggest they phone for a chat - that seems to sort the wheat from the chaff.
It would seem that I just have an apricot boy and a red boy available for sale. Two of the girls are being held on option for breeder friends of mine (depending on vet checks etc). They may become available later on, if they prove not to be suitable for showing or breeding.
I just love this litter, they are a joyful bunch and a source of endless amusement (unlike their aggy bag of a mother).
As much as I love this breeding lark I must admit that I'm looking forward to a few weeks as a kitten free zone.
