I just got a new 1 year old cat on January 31st 2021. He's of course hiding, which is understandable. He's a domestic medium hair cat.
Last night I went to sleep and he just kept meowing like crazy, my boyfriend went to check on him in his bed and he was fine, so we let him be.
Today as of right now at 9:47pm he has not stopped meowing under the couch. I went to check on him and he seemed fine. I slowly brought my hand towards him and he hissed, so I let him be. However, now he's just keeps meowing they almost sound like howling meows. Please someone answer as soon as possible! I'm starting to get worried for him!
