What happens when a cat is reincarnated? Or a cat? Will I ever see her again?

It seems that the landlord has deep feelings for your cat! This also shows that the fate between you is also very deep. Under normal circumstances, you will still have a deep fate in this life or the afterlife, but you can't tell what image she appears in. Because cats generally eat more meat, fish and so on. They may fall down after death, or they may be reincarnated because of their good deeds in their previous lives. So please take good care of other small animals around you, because it is hard to say that it is not the rebirth of the poor cat, because only sentient beings closer to you will come to you.

In addition, just to be on the safe side, I suggest you read more Mahayana classics such as The Diamond Sutra or The Wishing Sutra of the Earth Treasure King and Bodhisattva for her (that is, after reading it, you silently hope that this meritorious cat can get it and get a good place). I believe your thoughts and fate will be useful to her. Maybe she will be your child (no kidding), or maybe she will be a fairy because of your kindness.
