I took a copy of Unadulterated Cat to Sharlene in Tucson. She loved it, but was annoyed to discover that the book wasn't available in the US. She contacted her friend at Harper Collins about it, but it never came to anything.
I'm sure Americans would love the book too.
If you enjoyed Unadulterated Cat, you might want to see if you can find a copy (out of print now) of
The Silent Miaow by Paul Gallico - it's a delightfully funny book and, like Unadulterated Cat, very true. Any cat owner will recognise this one.
