Cat grass is a very easy plant to grow. Why have you never grown it before? I have interplanted barley and wheat here, and the cats enjoy eating them.
It is not advisable to take cats out to eat weeds outside. The possibility of the grass being contaminated is extremely high. What is even more worrying is whether chemicals such as insecticides and herbicides have been sprayed. Picking weeds from outside or feeding weeds to cats will compromise your safety, because some plants are poisonous to cats. The reason why people on the Internet recommend growing cat grass by yourself is because it is natural, clean and can be eaten with confidence.
I am not complimentary about the hair removal cream. It is made of various chemical ingredients. The main ingredient is oil (mineral oil). In order to improve the palatability, maltose is added to it. In order to make the texture become an ointment, some additional ingredients are added. Emulsifiers and preservatives are added to prevent the product from spoiling and preserving easily. Generally speaking, this is for emergency use. When the cat's hair ball syndrome is severe, it is suitable to apply hair-removing cream. Eating it every day is not necessarily a good thing.
There are several natural hair removal methods:
The first choice is self-sown cat grass (barley, wheat, oats, rye, rice and foxtail grass). Next is vegetable puree (take a small amount of pumpkin/spinach/carrot/sweet potato, choose one of your choice, cook it by steaming, then crush it into puree, without adding any seasoning, feed it directly 5g each time). Cats also like to eat water bamboo as cat grass, which is a kind of plant that is so slender that it looks like it has no umbrella and only the ribs are left. It is also known as umbrella grass (remember, it is definitely not the one we put in vases). Lucky bamboo is not Asparagus, Chlorophytum, Pothos, nor Dieffenbachia and Narcissus. Cats may die if they accidentally eat Dieffenbachia and Narcissus! )
In addition, the fur canned products of Rican Fiber Story are also very good. Cat grass hair removal relies on fiber to increase gastrointestinal peristalsis and bring out the hair balls. Fiber Story takes this principle and uses a large amount of fiber to remove hair. But the quantity must be controlled, and you can only give one can a week.
