Fatwans turned up at Toxic Towers in the summer of 2009, wearing a red collar. She was tiny, just barely grown out of being a kitten, and very very skittish. It turned out that she lived a short distance away, but was struggling there due to the presence of other pets and small children.
We found out on the grapevine that her name was Comfort, because she likes the smell of fabric softener, and sleeping on clean washing, Well, I wasn't going to call her that. Her temporary name was Little Friend, but that didn't really suit her either.
Via some neighbours that knew the original owners, I made sure that the transfer of Little Friend to Toxic Towers was with their blessing. When we heard that they were fine with it, I took her red collar off, and called her Fatwans.
