Before fostering a pregnant cat, coordinate with the shelter or rescue that placed her and establish veterinary and emergency contacts. Prepare a quiet, warm nesting space, follow veterinary guidance on food and health, and know which labor signs need prompt help. Each cat and foster program is different, so the organization’s care plan—not a general article—should guide decisions for her and her kittens.

What to arrange before the cat gives birth

Ask the responsible shelter or rescue for its written care plan before or soon after the cat arrives. Fostering arrangements differ: one program may supply equipment and schedule frequent check-ins, while another may handle support differently. ASPCA describes foster care as providing a safe environment for animals in need, but its program details do not establish what a local rescue will provide.

Get clear answers to these questions:

  • Which veterinarian should assess the cat, and how are routine appointments arranged?
  • Whom should you call after hours, and where should you take her in an emergency?
  • Who provides food, bedding, and other supplies, and who is responsible for veterinary costs?
  • How often should you report on the cat and kittens?
  • What is the plan if the mother cannot nurse or care for the litter?

ASPCA’s kitten nursery guidance notes that many kittens need recheck visits; the frequency and support available depend on the specific program. Contact your local shelter or rescue rather than assuming you qualify for or will receive a particular organization’s services.

How to think about the due date and veterinary assessment

VCA Animal Hospitals gives feline gestation as 60–67 days, averaging 63–65 days. These figures are general ranges, not a dependable due-date calculation when the mating date or pregnancy stage is unknown. Arrange a veterinary assessment through the rescue to discuss the cat’s health, likely stage of pregnancy, and any appropriate examinations. Do not arrange imaging on your own; a veterinarian can determine whether it is indicated.

ZOMISIA Cat Heating Pad, Heated Cat Bed Indoor, 11 Temp & 25 Timer Settings
  • Key Safety & Usage Guide: 1. Critical: Always ensure your pet lies over the center thermostat to activate auto-shutoff. 2. Never fold, bend, or cover the pad to prevent overheating. 3. For small pets/kittens, center them carefully and monitor during initial use.

Please read the instruction manual provided with the product before use to ensure proper and safe operation.

How to prepare the nesting space

Set up a quiet, private, warm place with clean bedding that can be changed. Make it easy for the cat to enter and leave, and position it so you can observe her without disturbing her. Keep her indoors as labor approaches so you can monitor her. VCA describes nesting behavior during the final week, but a cat may choose a different safe spot; do not force her into a particular box. Ask the rescue for advice if you are unsure whether her chosen location is suitable.

What to feed her and what not to supplement

VCA recommends a high-quality commercial kitten food or growth-formula diet during pregnancy. Portion needs vary, so monitor her body condition and ask the veterinarian about feeding amounts rather than relying on a universal calorie target. Avoid both overfeeding and underfeeding.

Do not give calcium supplements or other supplements or medicines unless the veterinarian directs you to. VCA warns that excessive calcium during pregnancy or nursing can suppress parathyroid hormone production and increase the risk of eclampsia, a life-threatening fall in blood calcium in nursing mothers.

What labor may look like—and when to call

As labor approaches, a cat may nest, become restless, groom herself more, pant, or stop eating during the final day. Intervals between kittens can vary, and some cats pause to rest. Observe calmly and avoid unnecessary handling or anything that upsets her.

Have the rescue veterinarian’s emergency number ready before labor begins. VCA advises immediate veterinary attention for the following signs:

  • Twenty minutes of intense labor without a kitten being born.
  • Ten minutes of intense labor when a kitten is visible at the vulva but does not come out.
  • Gentle traction causes the cat pain.
  • The cat is lethargic or has a rectal temperature above 103°F (39.4°C).
  • Fresh bleeding continues for more than 10 minutes.

These are published warning thresholds, not a reason to delay a call if the cat appears seriously ill or you are worried. Labor can be difficult to assess remotely, and clinical guidance can vary; call the rescue or veterinarian promptly for advice.

Toozey Cat Heating Pad for Cats & Dogs, Heated Cat Bed Mat, 18x16 in, Grey
  • SMALL SIZE THAT MAKES SENSE FOR CATS — If you are shopping for a cat heating pad, size matters more than people think. This 18 x 16 in heated pet mat fits cat beds, condos, crates, and tucked-away sleep spots without taking over the room, which makes it feel like an easier yes for apartments, bedrooms, and smaller indoor setups.
  • A WARM SPOT YOUR CAT IS MORE LIKELY TO CHOOSE — Cats do not care about feature lists; they care about whether a place feels cozy, safe, and worth curling up in. This small heated pet mat helps turn a cool corner, cat bed, or favorite perch area into a warm resting spot that feels more inviting on cold mornings, winter nights, and drafty days.
  • SIZE GUIDANCE FOR SMALLER PETS — Best for cats, kittens, toy breeds, and other small pets that prefer cozy, compact sleeping spots. A great fit for many smaller pets under about 12 lb, depending on sleeping style, bed setup, and whether your pet likes to curl up tightly or stretch a little while resting.
  • ADJUSTABLE HEAT FOR REAL-LIFE COMFORT — With 6 heat settings from 86-131℉, this cat heating pad gives you more control over how warm the surface feels depending on the room, the season, and your pet’s comfort level.

What to do after the kittens arrive

Usually, the mother opens each kitten’s membrane, clears its face, severs the umbilical cord, and begins caring for it. Follow the rescue and veterinarian’s instructions after delivery. VCA recommends a veterinary examination of the mother and litter within 24 hours; contact the rescue promptly if the mother seems unwell, rejects a kitten, or the kittens are not nursing.

Maternal milk is preferred whenever possible. If the mother cannot nurse or care for the litter, contact the rescue or veterinarian immediately for instructions; orphaned or non-nursing kittens may need kitten milk replacer and intensive hand-rearing. This is a contingency, not a reason to supplement kittens who are nursing normally without veterinary advice.
