Hi have taken in a cat, heavily pregnant. Last day or two won't leave me, more vocal although she does talk anyway. I've left nests all around in one room, under bed in cupboard etc. She's been in and out of them all today. She's started to want belly rubs and petting. She's started scratching at the floor, rug, walls, outer cardboard of nest box, etc which hasn't happened before. She was eating constantly but last couple of hours her appetite has stopped. She's using her kitty litter tray happily without fussing or crying for a change! Lots of napping, purring and pacing. Seems content but I'm thinking these are all pre labour signs? She's in my room so so I can sleep/wake through out the night if needed. How long should I be waiting for her to start active labour? Thank you and any advice welcome. (already eating kitten food, flea treatment, worming done, vet could feel 3/4 kittens moving around couple of days ago)
