My kitten is 8 wks old. She is litter box trained. Twice now, she has started scratching the ground next to her litter box and crying, the first time she peed on the carpet, the second I was able to move her to her litter box in time, but she pooped. What I'm concerned about is the fact that she's crying when she does this, and also that she goes in the litter box every other time she needs to potty... and there's no crying or other strange behavior. I'm not sure if I should just keep and eye on it, or if she needs to be seen???
