Plush Lops reach sexual maturity at a relatively young age, with small-breed rabbits generally becoming capable of reproduction between three and a half and five months. However, physiological capability does not equate to breeding readiness, and responsible breeders distinguish carefully between the two. A Plush Lop should not be bred until it has reached physical maturity, which occurs between six and eight months of age for this breed, allowing the skeletal and muscular systems to develop fully before the demands of pregnancy and lactation are imposed on the doe's body.
Assess breeding readiness through a combination of age, weight, and overall health evaluation. A Plush Lop doe intended for breeding should weigh at least three pounds and be in optimal body condition, neither overweight nor underweight, with a healthy coat, clear eyes, and no signs of respiratory illness, dental abnormality, or musculoskeletal problems. Bucks should meet the same health criteria and should have both testicles fully descended into the scrotum, which typically occurs by four to five months of age. A pre-breeding veterinary examination for both animals is strongly recommended.
The mental maturity of the breeding pair matters alongside physical readiness. Young does that have not yet settled into a stable temperament may be more likely to reject their kits, fail to build an adequate nest, or become excessively stressed by the breeding and pregnancy process. Bucks that are bred too young may lack the confidence or coordination for successful mating. Allowing both partners an additional month or two beyond the minimum maturity threshold results in calmer, more predictable breeding behavior and better maternal outcomes.
Female rabbits are induced ovulators, meaning they do not have a fixed estrous cycle like dogs or cats. Instead, ovulation is triggered by the physical act of mating. Does are generally receptive to the buck when the vulva appears reddened and swollen, though receptivity can fluctuate. A doe that is not receptive will flatten herself against the floor, run from the buck, or vocalize in protest. Never force a mating on an unreceptive doe, as this can result in injury to both animals and psychological trauma that may affect future breeding willingness.
