K I KNOW it ent by this person...whoever she is...oh! Steven Moore! thats who it's by I remember it now...here's a review...
'Bryna is a proud cat living in your ordinary, full of other cats and dogs. But one day, the humans leave and they're in a hurry. But why did they leave? The humans leave with such speed that they leave the pets, beloved dogs and cats behind them. Bryna, Treacle, Dexter, Fat Blossom, Kim, Yip yap and so many more wonderful characters fill this book with brilliant adventure. It is brought to life by Moore's incredible description powers. Brian Jacques has commented on this book himself! But something is coming. Something that takes lives in a single blow. Something far more powerful than any dog or cat can ever imagine. And it's coming. Time is running out for the pampered pets and they must join forces. Can Bryna and Kim get the dogs and cats together? And most importantly, can they do it in time?'
Does this have any resemblence to...Doranna Durgin's book at all?
