I used Kintraks years ago. Then it got glitchy & I lost data
Once I found globalpeigree.com I never looked back.
I have been using since 2013 & I am SO grateful.
When I first started, Jeremy the owner, was available to fix and problems or answer questions in a forum.
Now that he has almost 10,000 users he no longer has the time for that but it's still a GREAT deal.
I paid the LIFETIME membership fee years ago and have TOTALLY found it worth it.
It only costs $20/ a year if you don't want to spend the $125 for a lifetime membership.
It tracks everything.
One of the most fun things is the "possible breeding" feature, which shows you the possible kit color % for any pairing. Of course, it's most accurate if you know the total genotype, but still informative.
Over the tears I have emailed him to ask for him to add things, like the Amber color genotype for Rex.
He has always been helpful.
It's great to be able to search the rabbit database for the more that 223,000 listed there. you can search by "owner" too and then you can message the owner if you want. to discuss a particular rabbit. There are over 9800 members.
Its easy to jump around in the pedigree and to update rabbit weights and save notes on breeding, sales, picctures, etc.
I can't say enough good things about it!
