Is this possible?!
I have the ginger boy (Scabbers) and also a tiny little tortie girl, Millie, also neutered, both 18 months or so old.
The other night when I got into bed, they both woke up (lying at the foot of the bed) and Scabbers decided to grasp Millie's head and wrap himself round for a cuddle! She looked most uncomfortable (she reminds me of me!) and leapt off.
This morning I was sitting down having a coffee with Millie, and Scabby leaps through the catflap with a huge vole in his mouth. Now usually it's woe betide anyone who tries to remove his kills...but this morning he dropped it at Millie's feet and lay down in a very self satisfied manner while she had fun tossing it about and pouncing.
What's going on?! He was very wary when I first got her - now I think he's got a bit of a crush! 
Note: yes I have got too much time on my hands.
