"Staff quickly realized this group of cats and kittens was related to the previous ones as most are black and white 'tuxedo' cats," MHS said in a release. "In total, more than 130 of these cats have been abandoned at the shelter over the last four years. None appear to have been spayed or neutered."
The kittens appear to be the results of irresponsible breeding, according to MHS.
"While we're grateful the kitties are safe with us, we want to find out who's responsible for the overbreeding so we can offer assistance - for any cats remaining and for the people involved," Lisa Bloch, a spokesperson for MHS, said.
