My kitten was spayed today. The advice sheet says to keep her indoors for 7 days. However, she's been home since 3pm and is desperate to get out. She's scratching the door, pulling up the carpet and howling at the door in her desperation to go out. I've tried keeping her calm but she's not interested despite usually being very affectionate. She's eating and drinking normally , but when she does so, it's the only time she's not crying to get out. I've got her a litter tray but she's not used it at all and won't leave the (locked) catflap alone. She has one dissolvable stitch, doesn't appear in any pain nor tired. Does anyone have any advice? I fear I may crack and let her out for a few minutes. I'm not even sure why cats are not meant to go outside after the procedure. I'm guessing for infection reasons.
