Spraying mosquito-killing drugs on residential properties in rainy days and killing three cats, is there justice?

Residential property is also for the benefit of residents. The cat was an accident, and the property didn't want it. As for the mosquito not being killed, that's your misunderstanding. Think about cats. Drugs can kill them, but mosquitoes can't escape. It has just rained, and mosquitoes breed faster and more in humid environment.
