This was a little bit difficult for us to read, but if we understood correctly, this person is heating up cans of cat food in the microwave. That does not sound like the best idea seeing how the metal of any kind inside the microwave is very dangerous. It’s probably the first rule of how to use a microwave.
We do not know how long this cat will have to live if its owner is this stupid. We sure hope that someone identified this person and called animal services to come and collect the cat from them. The poor little thing must be starving from not getting any cat food in days.
