More Tips!
 

Teeth

Baby teeth:
2 weeks – Deciduous incisors (the small teeth at the front) begin to come in.
3 – 4 weeks – Deciduous canines (the long, pointy teeth next to the front teeth) begin to come in.
4 – 6 weeks – Deciduous pre-molars (also known biscupids, these are the teeth located between the canine and molar teeth) begin to come in.
8 weeks – All baby teeth have come in.

Adult teeth:
12 – 16 weeks – Incisors come in.
4 – 6 months – Canines, pre-molars & molars come in.
7 months – All adult teeth should be fully developed.

 

Eyes
Kittens are born blind, but after a week their eyes begin to open and after ten days their days should be completely opened. Kittens are all born with blue eyes, which will gradually change color as they mature. The eyes will usually change and settle 7 weeks after birth. If the orphaned kitten still has blue eyes, it is probably under 7 weeks of age.

Litterboxing
Very young kittens — under the age of 3 weeks — will not be litterbox/toilet trained and will need to be stimulated to pass a bowel movement along with urine. (Observe the kitten to see if it’s trying to use the litter tray. If not, use a moist paper towel or a wet flannel, which will resemble the mother’s tongue, and massage it over the kitten’s bottom until the kitten has passed a bowel movement or urine.)
