For novices, it is better to keep one cat or two? This needs to be determined by the individual situation, and if you have enough time and energy to take care of them, it’s OK to keep one or both. If you don't have enough time to take care of them, it's better to just keep one.
Raising a cat will be more worry-free for the owner. If you raise two cats, you must prepare two servings for all the cat supplies, and the demand for cat food will increase and the number of times shoveling will increase, but the cat will not feel lonely when staying alone at home.
For cats, companions are very important. Raising two cats can reduce the risk of cats' stress response and will give the owner more space. The cat will not stick to the owner all the time. However, if more than one of the two cats raised has a bad personality, there will be a fight.
