Billy Slipper is just a normal boy. Sort of. Bu one day he finds a completely jumbled-up, legs-head-and-tail-all-over-the-place, grumpy, enormous, biscuit-obsessed TALKING cat - and everything changes! Billy decides to keep the cat but his cleaning-mad mum, his horrid sister, and a barmy old army colonel who loves stuffing unusual animals have other ideas... Can Billy save the day, or will Jumblecat suffer a fate worse than being deprived of biscuits?
