Ten cats were found dead in a yard in the Hammocks on Monday morning, and another three were so ill they had to be euthanized. One of the cats was found with signs of head trauma, but authorities suspect that all of the felines were likely poisoned.
According to WSVN, Animals Services responded to call that several dead cats were in a yard in the area of the 10000 block of Southwest 147th Place.
The cats were all likely strays, but a neighbor tells NBC Miami that the cats were regularly fed by the owner of the home.
Several other live cats were found in the area, but Animal Services has set traps to try and catch them and test them for poisons.
"It's extremely unusual for this many cats to be found dead in one area," Animal Services spokeswoman Kathy Labrada told NBC.
Back in 2009, a string of cats were found killed around Cutler and Palmetto Bay. Teenager Tyler Weinman was eventually arrested, but charges were later dropped after animal bites were found on the corpses.
