May I ask how much you guys spend in a month on cat food? I kinda dare not count the cost because mine are mainly eating wet food so the money spent is substancial.

they usually feed  Bayer's Velcote.

Just saw this message.  I hope your kitten survived.  My cat delivered 6 kittens and 2 were stillborn.  The last one is the runt of the litter and we were worried it would not survive (bald headed and very weak).  It was back in November during CMCO and we called nearby pharmacies to find out whether they sell milk powder and feeding bottle/syringe for baby kittens.  After that we had to help the runt get enough milk from mother cat during every feeding then supplement by bottle feeding every 2 hours.  By the time he's 1 month old he slowly grew stronger and growing more hair.  By 2nd month old, he's starting to look handsome.  Now he's the fattest/heaviest and most handsome out of the litter and is well loved by everyone.  We're really thankful we managed to save him.

If got mum. Lock them inside room. Mum should take care child naturally I guess. I raised 2 families before. Don't even need bother the child until month 3, cause mum is there.

maybe need a little help by force feeding wit a 1 ml syringe every 2 hours? looks like too small n maybe no energy to compete with the others for mum's milk if dont force feed  for all we know the little guy might be born premature therefore will need some help

Just read your message.  FYI, we use 1ml syringe and slowly 'shoot' in the mouth (careful not to choke the kitten or hurt the mouth). Kitten powder milk is only as supplement (preferably every 2 hours if it's not drinking mother cat's milk) because most important is the mother cat's own milk. We also help the kitten to find and latch on to the mother cat's nipple and take other kittens to put on another nipple if they try to 'fight' with the runt because the runt is too weak to fight on its own.  It will drink milk a while then sleep so we have to wake it up gently and put it to the nipple again.  Sometimes need to tell mother cat to stay still and pet/encourage her to take care of the runt.
You can observe if mother cat totally don't care about the kitten which means survival rate of the kitten is slim unless you help it.  We noticed cos mother cat has other kittens fighting over her nipples and is too tired to really care about the runt who's not latching on so we keep bringing it to her to lick/clean.  If mother cat did not clean the kitten, you need to take cloth (wet with warm water) to gently stimulate the kitten's bottom so that it will poop/pee.  Try to google 'how to care for runt kitten' and read/watch videos.
We are so thankful ours survive and is now the 2nd biggest size out of its siblings.
Best of luck.
