Cat Feline Neonatal Hypothermia Prevention

Hypothermia is the leading killer of neonatal kittens and is entirely preventable with appropriate temperature management.

Key Facts

Kittens cannot shiver to produce heat until approximately 3 weeks of age
Optimal environmental temperature for neonates is 29 to 32 degrees Celsius in the first week
Hypothermic kittens cease nursing, become lethargic, and develop hypoglycemia rapidly
Gradual rewarming over 1 to 2 hours prevents cardiovascular shock from rapid temperature change
Heated pads, heat lamps, and incubators all provide effective supplemental heat when used correctly

Welfare Considerations

Kittens dying from hypothermia experience progressive weakness, loss of consciousness, and death within hours of becoming cold. This entirely preventable cause of death represents a major source of neonatal suffering that proper heat provision eliminates.

What You Can Do

Monitor environmental temperature in queen's nesting area and provide supplemental heat if below 25 degrees
Learn to recognize hypothermia signs including limpness and cold feel in kittens
Contact a veterinarian or rescue organization immediately if orphaned kittens are found
