I found an abandoned 4 day old stray kitten. She is 30 days old now. She is doing great, eating well, putting on 10-15g every day, playing, pooping- peeing etc. I just started her on kitten food and milk too. She is not happy eating by herself yet so still bottle feeding her. Today I noticed she is not responding to sound. I have tried clapping behind her head, she does not respond to a small ball with bell in it. Not sure if she can hear or not. For her age she is very small. Today she weighted at 245g. She fits on my palm and is very tiny. Could it be that her growth is slower so she might take a little bit more time on her growth?
