I got a new cat yesterday, she's 2 years old and needed to be re-homed. The move has been very stressful for her but I've been providing her with everything she needs: a safe room with food, water, a litter box and beds. She's been eating but she refuses to drink water, it's been about 24 hours since we got her and I'm getting worried that she'll become dehydrated. What should I do?
