Answer:
Monitor
Step-by-step explanation:
When you adopt an animal, not only do you have to take care of them, but you need to watch for signs in your pets for any sickness or illnesses. You can check for changes in their normal behavior, fur changes, decrease in appetite or energy level, blood in urine or stool, hiding, increase shedding or bald patches. And that's when the word "monitor" comes into play, you are 'monitoring' your pets for any abnormal changes.
Hope this helped :)
