Recently my mom found a kitten abandoned on the highway and took him home. He was pretty beat up but is doing substantially better. It's nearly been a week now since we got him. He eats like crazy which is expected. Wet and dry kitten food. Uses the litter box and is very loving and playful but he is SUPER vocal. He does not stop crying! It is starting to get out of hand. What do I do and what could possibly be a cause of this? Is it because he was abandoned? How do I help!?
