Yoshi is about six. He was rescued from a kill-shelter by a woman running Refuges St-Chatques (a play on words for St-Jacques). I found Yoshi last year on http://petfinder.com .
Jacob is about seven. Jacob came from the Montréal SPCA Annex over three years ago – one of the last of the colony of around 90 cats from a hoarding situation in a 3-1/2 apartment in NDG. (Montréal speak – a 3-1/2 is a one bedroom.)
