Newborn cat
All that you need to know

- Body temperature: Newborns cannot regulate the body temperature efficiently and they lack of shiver reflex, so hypothermia is an easy situation that we need to avoid. We need to keep they warm.
- Suckle reflex: Neonates should have strong suckle reflex, if this is not present or weak, may indicate health problems and the animal may need a feeding tube. The suckling reflex usually disappears after approximately 20 days (1).
- Weight: Normal kitten should gain 10–15g/day, and double their birth weight before the 2nd week. If the kitten is not gaining all the weight that should, it may be related with the kitten itself, but it can also indicate other problems, for example: that is the weakest of the siblings, that the mum has problems in the mammary glands… Supplementation using cat’s formula should be started as soon as possible.
- Voluntary elimination: it starts at 3 weeks of age. During the first 3 weeks if they are with the mum, she is going to stimulate them to urinate and defecate, but if they are orphans, it is the caregiver’s job to stimulate them with an anogenital massage after feeding. The anogenital reflex disappears between 23 and 39 days.
- Senses: after birth only tactile, flavour and olfactory senses are active, hearing will appear at 5 days (but does not orient to sounds until approx. 2 weeks old) and sight will start progressively improving after opening the eyes at 7–10 days of life.
- Grooming: self-grooming begins at approximately 2 weeks of age, but the kitten’s efforts are clumsy and incomplete. Again, is the mum’s job or the caregiver to keep them clean.
- Social relationship: at 4 weeks the kitten begins to move away from the nest and develops social relationships with people and other animals in its environment. You can check our kitten socialisation post.
- Solid food: At 4 weeks weaning begins, and kittens begin to eat solid foods. By 7 to 8 weeks weaning is largely completed, although suckling may continue intermittently for several more weeks (2,3).
