Instincts are useful but don’t forget about the vet.
All animals, both wild and domestic, perfectly mastered the principles of self-treatment for thousands of years. Animals are all different, but in the case of illness, they often do the same. They refuse to eat, but they drink a lot of water. They try to stay behind while choosing the warmest place to spend less energy on warming the body. Being outdoors, the animal will easily find the necessary medicinal plant and will eat it. But animals cannot cure all diseases themselves. Therefore, your pet should regularly visit the vet.
