This is Tinks and he could be Britain's fattest cat. Along with seven dogs he will be competing to win the title of the UK's biggest animal slimmer. Tinks weighs over 11kg and as a result suffers from heart problems and spends most of his time sleeping. This is one seriously fat pet that really needs to go on a diet and exercise program to lose some of that extra fat. Lets hope the 100 day fitness program will help him to do this. He makes my cats look thin in comparison.
