A female cat can get pregnant when sheâs as young as 4 months old, unless sheâs been spayed to prevent that. Queens can keep going into heat every 2 to 3 weeks from the spring through the early fall, making them ready to reproduce more often than not. A catâs pregnancy lasts about 63-65 days.
But research shows that healthy kittens can be safely neutered at 6 weeks, or as soon as they weigh 2 pounds. Referred to as early-age, pediatric, or pre-pubertal spay/neuter, the procedure eliminates any chance of an âoops litterâ since female cats can become pregnant as young as 4 months of age. Early-age spay and neuter is safe.
