Hello. I have a kitten that is possessed(sp?) with heat cycles right now. I feel so bad because she acts like she's completely miserable. I read your posts, and tried confining her to a bedroom with litter box, food/water, her bed, etc., and she freaks out and has been tearing up the bottom of the door, and last night I found that she has torn the carpeting right by the door! We've been going thru this for a few weeks, and it will be another week before her appt. to get her fixed. I have been trying to distract her or keep her mind on other things, like playing with her ball~this kitten was born to play soccer, and to fetch balls, she catches them, stops them, and can launch it at me with her paws, and has just dropped one in my lap telling me, "ITS TIME"~my arm is sore from throwing this thing!!! Anyway, I can't confine her, so we are ALL going thru this craziness together. It will be nice to get my cat back, and be able to get some sleep at night. I just hope she isn't too miserable.Queens in estrus will often break from normal, appropriate litter box behavior during their cycle. A lot even spray - it is their way of depositing their scent for males to find them so they can breed.
Keep her confined to one room, preferably a dimly-lit, cool room with her litter box, food and water bowls - it will ease her symptoms a bit and provide you with a safety net against accidents (which really aren't accidents at all - they are quite on purpose).
