A few common questions
Can appearance confirm a kitten's exact age?
No. The result is an estimate. Orphaned, sick, underweight, or injured kittens need rescue or veterinary guidance quickly.
Which signs matter most?
Weight, eye opening, ear position, tooth eruption, walking stability, and whether the kitten can eat independently all help narrow the range.
