They say the unleashed dogs mauled their cat while the owner stood by and watched.
It happened outside their home in the Lafayette section of Jersey City on Nov. 19 at 6:30 p.m.
Santanu Roy ran outside and kicked one of the dogs off the cat, but it was too late.
The owner said 'my bad' and then left with his dogs, according to the Roys.
Authorities have not been able to identify the dogs' owner.
