Maine Animal Shelters say this time of year they take in a larger than normal number of stray cats and dogs.
Bangor Humane Society Executive Director Suzan Prendergast says some of the animals may have gotten loose as their owners are engaged in outdoor activities. Other have run off after being scared by fireworks. The society says folks should leave their pets home during the fireworks.
Prendergast says, in general, pets don't react well to loud, booming noises.
"Whether it be a thunderstorm or a beautiful fireworks display, I don't think our dogs sit back and go 'Oh, look how pretty those lights are' they typically cower and wonder why is that so loud."
The Animal Refuge League of Greater Portland says July 5th is their busiest day all year.
Prendergast says people should make sure their pets have identifying microchips or tags so if they do get separated from their owners, they can be returned as soon as possible.
