Early weeks and confirmation
Feline pregnancy typically lasts around 63 to 67 days, counted from the successful mating. In the first two to three weeks the changes are subtle, so it is easy to miss that your queen is expecting at all. Around three weeks in you may notice her nipples becoming pinker and slightly enlarged, a change breeders often call pinking up. A veterinarian can confirm the pregnancy by gentle palpation from about three to four weeks, or by ultrasound a little earlier. Keep her routine calm and unchanged during this settling-in period, and let your vet guide any early questions.
Mid-pregnancy development
By the middle weeks the kittens are developing quickly and your queen's abdomen will begin to round out visibly. This is the time to gradually increase her food, ideally transitioning to a high-quality kitten or growth formula that supports both her and the litter. An ultrasound around this stage can confirm viability, and later an x-ray from roughly day 45 onward can help count the skeletons so you know how many kittens to expect. Feed to appetite in smaller, more frequent meals as the growing litter leaves less room in her belly. Any sudden loss of appetite or discharge in these weeks is worth a call to your vet.
Late pregnancy and nesting
In the final two weeks your queen will often begin seeking out quiet, secluded spots, a behaviour known as nesting. Provide a clean, warm, draught-free kittening box lined with soft washable bedding, placed somewhere she already feels safe. Let her explore it early so she chooses it herself rather than settling behind the sofa or in a wardrobe. Her appetite may become less predictable and she may grow more affectionate or more withdrawn. Have your birthing supplies and your vet's out-of-hours number ready well before the due date.
Signs labour is near
As birth approaches you may notice her body temperature dropping slightly, often below 37.5 degrees Celsius in the day or two beforehand. She may become restless, pace, pant, refuse food, and visit her nesting box repeatedly. Some queens vocalise more or groom their hindquarters intensely as contractions begin. Once you see her settle into the box and start straining, active labour is underway. Stay calm and nearby, keep the room warm and quiet, and contact your vet promptly if anything seems to stall or distress her.
