BOSTON, Mass. (WWLP)--From saving Nibi the beaver this fall to signing a new puppy and kitten law on Wednesday, Governor Healey has been hard at work to fight for animal welfare. The legislature sent this law to the Governor on December 30, during a marathon session to close the books on as many laws as possible before the final gavel of the lawmaking term. New Massachusetts laws put limits on dog, cat sales This new legislation makes it illegal to sell puppies and kittens who are under 8 weeks old. Reasoning behind this rule stems from public safety concerns--animals who are separated from their mothers and littermates too early are more likely to develop health and behavioral problems, including biting--which could put the public at risk. This regulation was already in place for pet shops and shelters and now extends to all individuals. The law also limits where puppies and kittens can be sold and prohibits sales at flea markets, roadside stands, and parking lots, among other locations. This rule does not apply to puppies and kittens being transferred to licensed shelters or rescue organizations, or to animal control. The law does not impact individuals' ability to display dogs and cats at the Big E or other fair exhibitions and 4-H programs. Each violation of these new provisions results in a monetary fine, ranging from 50 to 300 dollars, depending on the offense. This law joins a suite of animal rights laws passed last session, including Ollie's law that makes doggie daycare safer for your pets and a law that prohibits circuses from using certain animals in their acts.
