More time for the cats you love. Less time trying to remember where you put everything. Raising kittens is already a lot of work. And somehow, that’s only half of it. There are vaccines to remember, weights to track, breedings and appointments to schedule, deposits to record, families to keep up with—and about 29 other little details you were definitely going to remember. We made keeping track of all of it a whole lot easier. The Cat Box is an iPhone app made specifically for cat breeders, created by a Bengal breeder and her iOS developer husband. It brings your cats, litters, kitten families, photos, health records, breeding plans, appointments, and all those little details into one organized place. MAKE PHOTO DAY WAY EASIER Start a Photo Shoot, choose your kitten, and start snapping. Photos and videos from that session are automatically linked to the right cat. Switch kittens and keep going—no more staring at 75 photos later wondering, Wait… is that the pink collar kitten or the purple collar kitten? Add your cattery watermark when sharing while keeping your originals untouched. You can also import existing photos and videos. KEEP TRACK OF YOUR KITTEN FAMILIES Keep inquiries, waiting lists, contact information, kitten preferences, deposits, appointments, and notes together. So when you have three Ashleys on your waiting list, you’ll know exactly which Ashley wanted the brown female—and which one already paid her deposit. CATS, LITTERS & BREEDINGS — ALL TOGETHER Create profiles for your cats and kittens, organize litters, plan breedings, and track pregnancies. Keep photos, notes, contracts, documents, and important information attached to the cat, litter, or family they belong to. HEALTH RECORDS WITHOUT THE PAPER CHASE Track weights, vaccinations, health testing, deworming, parasite prevention, heat cycles, and more. Keep reports and documents right alongside each cat’s history so they’re easy to find when you—or your vet—need them. PLAN YOUR CATTERY Keep breeding dates, appointments, kitten milestones, go-home dates, projects, checklists, and follow-ups in a dedicated cattery planner. Because your brain already has enough tabs open. SHARE THE FUN STUFF Send photos and videos to kitten families or create newsletters for a kitten, litter, cat, or your entire cattery. Your families get the updates they love. You get a much easier way to send them. YOUR RECORDS STAY CLOSE Records are stored on your iPhone with private iCloud sync when available. Import supported photos, videos, documents, scans, and links, and create manual backups of your cattery records and files. START FREE Try The Cat Box for free. The free version includes limits on how many records you can add and edit, while The Cat Box Pro removes those limits with a monthly or yearly subscription. Photo sharing, watermarking, newsletters, iCloud sync, and backups are included in Free. Made by people who understand the work—and love—behind every litter. Less searching. Less remembering. More time for the cats you love. Download The Cat Box and put your cattery in one place. Pro subscriptions renew automatically unless canceled.
