For the fourth year, the popular 24-hour Mega-Match-a-Thon Pet Adoption returns to Miami. Hundreds of homeless dogs and cats of all breeds, sizes and ages will be looking for their forever families at the one-and-only petstravaganza. The Humane Society of Greater Miami Adopt-A-Pet, The Cat Network and local rescue groups will join host Miami-Dade Animal Services with their adoptable dogs, cats, kittens and puppies for a day filled with happy “tails” endings. There will be music and live entertainment from local performers and food trucks. Friday through Saturday, from 11:59 p.m. to 11:59 p.m. Adoption fees start at $30.
