[Mice may be responsible for a blaze that killed nearly 100 cats at an animal shelter near the Canadian city of Toronto, officials say.
The fire at the humane society shelter in Oshawa also killed three dogs and some rats that were up for adoption.
An initial report from the fire marshal says mice or rats chewing through electrical wires in the ceiling are likely to have sparked the blaze.
Offers of help have been pouring in from animal lovers across Canada.
"It's unfortunate and ironic that mice caused the fire that killed the cats," Toronto Humane Society spokesman Ian McConachie told the BBC News website.
"Unfortunately, the mice probably perished in the fire as well," he added.
The $250,000 (£137,000) fire is still under investigation by the Ontario Fire Marshal's office.
Mr McConachie said it would be some days before a final report would be released.
In all, only nine dogs, two cats and one rat were rescued in Wednesday's early morning blaze.
Matt and I are in Georgia now, getting ready to go up to the Toronto area. I will be on guard for any mice with matches and propane or possibly Molotov Cocktails being flung at our big rig, as we risk our lives while adding to Canada's pathetic GNP (while simultaneously shrinking our own trade deficit).
Though I think from recent experience that bats might have been in unison with the waywardly and genetically confused mice creatures that have started this insane war of terror, there has been no evidence to support this hypothesis. If any proof surfaces, I will scratch their little blind eyes out and rip their wings to shreds.
Isn't it strange that a rat was rescued, too? I'll bet the little rat bastard had something to do with it, and I can make him talk if necessary. Perhaps Matt will steer the big truck over to the shelter so I can question him thoroughly.
The grieving process must begin soon...and so close to Christmas.
