An animal welfare group in Ontario says more than half of nearly 600 domestic rats seized last year from an apartment in North Bay, Ont., have been adopted.

North Bay and District Humane Society spokesman Daryl Vaillancourt says "most" of the rats were running free in the apartment when inspectors went there on Dec. 16, 2016, to investigate a report of a large number of domestic rats being kept in an apartment.
