You need to know some basic knowledge and rules before you go to the temple to pray. First of all, you need to choose a temple near your home, and it is best to have a place to pray for pets. You need to pay attention to the time and way of prayer. Temples usually hold a blessing ceremony at a specific time. You can call in advance or consult the temple.
When you arrive at the temple, you need to enter the place where you pray, usually the room where you worship your pet idols. You need to drop your shoes and bow to your idol. Then, you need to tell your story and pray to your idol, so that your pet can get peace and happiness in the afterlife.
Finally, you need to pay a fee for prayer, usually a free donation, but you can decide how much to donate. Different temples, different ways of praying, the cost may be different, you can ask before you go.
In a word, praying in a temple can not only pray for the cat's afterlife, but also comfort his soul, but also need to choose a suitable temple and know the way and cost of praying. I hope you can find a suitable way to ease the sadness of losing your pet.
