Cats carry between 58 - 65 days. Usually 24 hours before the blessed event, they will stop eating - so that is your best clue. About a week before - They begin "nesting" - looking for a good spot to give birth. This is usually going to be a closet or under a bed. It is best to prepare a cardboard box that is closed on all sdes except an opening you have cut - about 4 inches up so the babies do not fall out. Just leave it and she will go in on her own. Make sure you change the bedding every day because she will move her babies if it is not clean. Some cats move them any way.
Make sure you feed her extra food so she can make good milk.
Please let me know if you have any more questions. I will be more than happy to help.
Best of luck with your upcoming blessed event.
Warmest best wishes,
LOL -I would LOVE one but I have two sixteen year old cats that would probably object.
Better get that box ASAP!
Please let me know when the blessed event occurs and how many little darlings there are.
