Summary
Neonatal kitten survival is strongly linked to birth weight and litter size. Factors like stillbirths, queen parity, and maternal weight significantly impact kitten mortality rates.
Area of Science:
- Veterinary Medicine
- Animal Science
- Zoology
Background:
- Neonatal mortality in domestic cats presents a significant challenge for breeders and veterinarians.
- Understanding factors influencing kitten survivability is crucial for improving neonatal care and outcomes.
Purpose of the Study:
- To investigate the mortality patterns of Domestic Shorthair kittens.
- To identify key factors associated with neonatal kitten death, including birth weight, litter size, and maternal characteristics.
Main Methods:
- Analysis of mortality data from 294 Domestic Shorthair kittens.
- Examination of stillbirth rates, gross anatomy, litter size, parity, and maternal body condition.
Main Results:
- Birth weight was a primary determinant of kitten survivability.
- Stillbirths accounted for over half of early neonatal deaths (0-3 days).
- Mortality was lowest in litters of 5 kittens and at the 5th parity; single-kitten litters had high mortality. Overweight queens had increased kitten mortality, while smaller queens had fewer but more viable kittens.
Conclusions:
- Birth weight and litter size are critical factors in neonatal kitten survival.
- Maternal factors, including weight and parity, influence litter viability.
- Targeted interventions focusing on birth weight and litter management can improve kitten survival rates.
