How do cats and dogs know to eat grass?

Cats and dogs don't actually "know" to eat grass in the same way humans do. They don't learn it from other animals or from us. Instead, it's likely a combination of instinct and physiological needs:

Instinct:

* тревопасни: While cats and dogs are carnivores, their ancestors were likely omnivores, meaning they ate a variety of foods, including plants. This instinct to graze may have been passed down through generations.

* повръщане: Някои експерти смятат, че яденето на трева задейства повръщането, което може да помогне на животните да се отърват от неправомерни материали или паразити в стомаха си.

Physiological Needs:

* фибри: Grass contains fiber, which can aid digestion and help with the passage of stool.

* Хранителни вещества: Some grasses contain vitamins and minerals that may be lacking in their regular diet.

* скука: Some animals may eat grass out of boredom or curiosity.

Важна забележка: Докато яденето на трева обикновено е безобидно за повечето котки и кучета, понякога може да причини стомашно разстройство или дори отравяне, ако тревата се лекува с пестициди или торове. It's important to ensure your pet has access to safe, untreated grass and to monitor their intake.

Ultimately, the reason why cats and dogs eat grass remains a bit of a mystery. It's likely a combination of instinct, physiological needs, and perhaps even boredom.
