Had a bit of a panic last night because of a total change in behaviour with Kitty (new cat owner alert!) so I had a quick look online and I think she may be in heat (body low, bum in air, tail up, yelping and generally looking sorry for herself). She's 5 months old (ish - we're not sure exactly) and due to be spayed in 2 weeks time. She hasn't been outside yet and won't be till she's done, she's eating and drinking like normal but the yelping is driving me a little crazy. Is there anything I can do to relieve symptoms or distract her from yelping all the time so both me and the cat can get some sleep tonight?
