Oh, my goodness, I have never had this much trouble with a mama cat!! Ok, the two cats were doing fine together, mama cat Sasha and female fixed Katrina except for Katrina hissing at Sasha since Sasha and the kits coming home from the vet yesterday. So, I let them both roam the house freely while I kept an eye, and then I had to leave for a few hours this am. I got back at 1pm and Sasha was at the door waiting (a usual thing for her) and when I went to check on kittens, they were gone. I looked everywhere I could think of!! I listened for meows in every room. Then I waited, thinking Sasha would go off to feed them. After an hour, she still hadn't. She went to look in the basket a few times, and came to me a meowed, but never left my sight. When I went searching for kittens several times, she followed. Katrina usually stayed close by too. I called the vet, who said they'd call back, but I had to leave before they did. I just got home 20 min. ago, Sasha waiting at the door, still no sign of kits, and msg. from vet said lock her up 1/2 to 1 hr and she should be worried about kits and go to them. So, she is locked up now in cat carrier and I hope this works. Right now I feel like the biggest worry wart!!
