njoys playing with me, that brings much happiness to me.

One evening, I noticed that my cat stopped playing. I looked up, and here, about three meters ahead of my cat, was a big mouse. It seems to be eating something, their little eyes turning to look around from time to time.

I held my breath and felt a bit exciting. I couldn’t help wondering whether my cat was able to catch so big mouse. Suddenly, he jumped at the mouse with his mouth widely open. The mouse tried to escape, and it was too late. The poor mouse was killed before it realized that what had happened. Then my cat held the mouse between his tooth and brought it over to me as if to say he had done a good job.
