One day he got lost in my room but I didn't look for him for a while.
How long had passed before you looked for him?
That's hard to say, I had a lot on my mind, maybe some minutes or an hour
That's quite a long period of waiting. It's important to always know where your pets are. Losing them, even around the house, can cause them to get hurt.
I don't like animals.
No wonder you didn't care to look for it because you are not a pet lover. That's cool, and I respect that, but why would you have pets in the first place. It's got to be quite tedious for you to look after it, so it would probably be a good idea to not get any more pets after this one.
