Animals are not unbreakable.
Animals are not as strong and persistent as it seems at first glance. However, most of them are rather tenacious, so their disease is first not visible. In addition, they are unable to report their pain. Therefore, we are obliged to constantly monitor their behavior and appearance so as not to miss symptoms of illness. Enough exact signs of illness are changes in appearance and behavior: apathy, inactivity, refusal to eat and diarrhea. Often, it’s “only” due to improper maintenance and feeding, but the consequences can be very unpleasant. Be attentive to pets!
