From Yahoo! News:
A Burmese cat named 'Doogal' is seen in this combo picture as it sits on a toilet in Sydney on May 3, 2005. Doogal's owner, Jo Lapidge, invented a toilet training system for cats called the 'Litter-Kwitter.' Lapidge said she was inspired by the cat 'Mr Jinks' in the Hollywood film 'Meet the Fockers,' and invented the toilet training system after teaching 'Doogal' how to use the loo. (Reuters/Handout)
