DNA testing.

Understanding what a cat may carry—even when that cat appears completely healthy—is an important part of thoughtful breeding.

Some hereditary conditions can be passed silently from parent to kitten because a carrier may show no signs of disease. DNA screening helps breeders identify these genetic risks, make informed breeding decisions, and reduce the likelihood of producing affected kittens.

What the results tell us

At The House of Neva, all parents have completed a comprehensive feline DNA screening through two established genetic testing companies. Parents were tested through Basepaws for 43 genetic health conditions and received 43 clear results, and Wisdom Panel for 49 genetic health conditions and received 49 clear results.

Both parents' DNA profiles also identified the expected longhair and colorpoint traits associated with Neva Masquerade cats.

All litters are tested negative for feline leukemia virus (FeLV).

DNA testing cannot screen for every possible health condition or guarantee a kitten's future health. However, it is an important part of responsible breeding when combined with attentive veterinary care and appropriate health screening.

Kittens are vulnerable to changes and stress

Kittens can be sensitive to change and may become stressed easily, so their new environment matters a great deal. A calm, quiet, and welcoming home can help a kitten adjust more comfortably. Providing a consistent routine, gentle handling, and a safe space to retreat to can support a smoother transition and help the kitten feel secure as it settles in.

Kittens can go downhill quickly, so monitoring their health and environment is important. Contact your veterinarian promptly if you notice a sudden change in appetite, energy, behavior, breathing, or litter-box habits.
