Thanks Dawn, that sound very similar to Rosie, sept she screams for Scotland 

Hiya Desley, We acquired Rosie round about June, that's when her lovely owners took her to the vet to be PTS because she meowed all the time 
and it was one of my neighbours who knew we'd lost Robbie put me in touch with the vet.

The story of meowing turned out to be a load of lies and Rosie is a typical cat (apart from the time she almost bit clean through my hand coz I rubbed her belly for a second too long 

Not sure how unspayed females usually act, just know they do additional things, I haven't seen Rosie do anything weird, she just gulps when she is purring (guessing she's swallowing excess saliva)

Hi Folks, it is I, I haven't left 

tho it has been a while 

Ok, wee update on the Madam known as Rosie, basically she has turned into a female version of Robbie, out most of the time, when she is home, just sleeps, she has fairly made herself known to the other neighborhood cats and made it perfectly clear that the presence of other cats will not be tolerated 

I haven't seen her fighting and she has yet to come home with scratches/scabs etc, but by jove she can scream  I haven't heard her in a while tho next doors Bella still frequent's the garden 

Rocky our Lhasa Apso is a little shite and will chase Rosie at any given opportunity, I keep telling Rosie to stop running and he will stop, but I think she likes the chase  stupid dog...

anyway, we come to the main point for this post, I was in the garden not 20 minutes ago and observed Rosie spraying against a fence (like a boy) 
I didn't know they could do that, this makes me worry tho, is she just simply marking her territory or is she on heat  although I asked the question multiple times if she was dressed, I never actually got an answer... I'm guessing they would act different if they were on heat? yowling and such, thankfully, I've not seen any strange behaviour

OMG I'm so sorry to hear this.  They only way to do it in that case is to use (borrow) a trap and transfer crate.  http://www.catactiontrust.org.uk/index.php/how-to-trap

he really does need to lose the pom poms for everyones benefit

make it nice and inviting ... bit of catnip spray on a towel in the bottom    Try covering the carrier with a towel as well.

Good luck.
