Both hair removal cream and cat grass are useful. Both cat grass and hair removal cream can help cats expel hair balls, but the specific effects vary from cat to cat. Cat grass helps cats vomit out hair balls by stimulating intestinal peristalsis. Hair removal cream can lubricate the cat's intestines so that the hair balls can be passed directly with the feces. Cat owners should choose appropriate products based on the specific conditions of their cats to help cats expel hair balls and prevent cats from accumulating too many hair balls, which may cause hair ball syndrome to affect the cat’s health.

The difference between cat grass and hair removal cream:

1. Different properties. Cat grass is mainly grass plants, such as barley, wheat, oats, rye, rice, foxtail grass, etc. Hair removal cream is a processed product whose main ingredients are water, maltose, starch, fructooligosaccharides, glycerin and very few "plant products".

2. Different modes of action. Cat grass mainly helps cats to vomit out the hair balls accumulated in the body by stimulating intestinal peristalsis. Hair removal cream helps cats lubricate their intestines so that the hair balls can be passed directly with the poop.

3. The scope of application is different. Cats do not spit out hairballs as soon as they are born. Before the cat learns to spit out hairballs, it is more appropriate to use hair removal cream on the cat. Generally speaking, cats only learn to vomit hairballs when they are 8 months old. It is not appropriate to feed cats grass before they are 8 months old to induce vomiting.

4. The advantages are different. Cat grass has the function of helping to induce vomiting and promote digestion of cats. Hair-reducing cream is safer, milder and more palatable than cat grass in inducing vomiting. The cat grass essence in it can help probiotics proliferate and protect the stomach; olive oil and lecithin can lubricate the cat. The intestines accelerate the excretion of hair balls and prevent constipation.
