After a cat dies, its body will begin to gradually harden in 30 minutes to 1 hour, and will become completely stiff after 12 to 24 hours. The reason why a cat's body becomes stiff after death is because the body's tissues are deprived of oxygen after death, and the synthesis of adenosine triphosphate in the muscles decreases. Muscles will remain soft and elastic only when there is sufficient adenosine triphosphate.

After the cat has passed away, it is recommended to bury it deeply or hand it over to a pet funeral company. If you want to bury it deeply, it is recommended to find an open space away from residences, water sources, etc. After digging the hole, you need to pave it with lime powder; if you choose a pet funeral company, you can consult the local pet company for the specific company. Generally, funeral companies have collective cremation and single cremation. There are two options, the owner can choose according to his own situation.
