Keep track of which rabbits or cavies are due to have litters, which rabbit litters are due to wean or process, and increase the productivity of your animals with WhosDue. WhosDue is a litter record keeping app that provides statistics to show you how your animals are performing in addition to keeping track of all of their litters. With WhosDue you can have all your breeding and litter record info with you wherever you are, and easily see who is producing well and who isn’t at any time without having to check cage cards, giving you the information you need to make decisions to make your rabbits or cavies more productive. Features: • See a list of who’s due to have a litter, which rabbits are due to be palpated, and which rabbit litters are due to be weaned or processed sorted by due date and grouped by Breed on the main screen. • Get a notification for rabbits that a nest box needs to be put in with the doe before the doe is due and another reminder the morning she is due. The number of days before the due date can be customized in the settings screen. • Get a notification when a rabbit is ready to palpate or a rabbit litter is ready to wean or process. Notifications can be turned on and off in the settings screen to customize which ones you get. • Get a notification for cavies that they are due at the beginning of the gestation range for cavies. • Quickly and easily see the survival rate or largest litter size of all animals of a breed ordered from highest to lowest.
