I love the description of Edwina becoming velcro kitty! We are not long back from holiday and one of our cats did this too. She also kneaded the bed a lot while we were trying to sleep. I think she was just desperately glad things were back to normal, rather than traumatised.

I don't have too much experience of introducing a new cat to an existing household (there are people here much better placed than me to give advice on that - all those people who number their cats in double figures!!) but if I had the choice, I would rather be in the house for a while after the introductions.

Have you phoned the Humane Society today?
