This is my first post on here, so first a quick hello to everyone on here!

I picked up a cat yesterday who has been homeless for a number of years, she had been fed (but not housed) on and off by someone for about 3 months. So she has had a hard time really.
So I brought her home with me at about 9am with the intention of keeping her in the front room for a few days while she adjusts. I spent all day in there with her, she was so content I got down on her bed with her stroking her with her being all snuggly and lovely. (she was purring like crazy!) I didn't have the heart to leave her so stayed with her. To my surprise after I had dosed off I awoke to her using the litter tray all by herself which was amazing, then after that she came straight back to her bed for more cuddles.
So by about 8-9pm I decided to let her have a mooch about the flat as all was going well, I went to lay down on my bed and she quickly followed me and stayed with me all night. Had a look at the litter tray this morning and she must have got up in the middle of the night, used the tray then got back on my bed! Even this morning she was all snuggly and lovely.
Then she decided to get up and go for a wander, and since about 9am she has been hiding under the kitchen sink behind the kick board.
I realise I may have made an error in giving her free roam of the house a little too soon, and the reason I have written a detailed post of yesterday is to give a clear idea just how well things was going. Could it just be that yesterday as nice as it seemed, overwhelmed her a little?
Would appreciate your thoughts.
Many thanks
Simon
