My kitten of 10 weeks seems like it's choking like it's gonna throw up. It actually did throw up once and has choked about 3-4 times within the last 3 weeks. Everytime it chokes, I put it in it's litterbox but won't stay there. Tonight, I put it in my bathroom because there's no carpet in there. What should I do in situations like this? What is causing him to choke a lot?
