On the other hand, some people do not like pets. When they see dogs or cats wandering the streets, they sometimes harm them. In extreme cases, some even kill these animals and discard their bodies carelessly.
Tips for improvement:
1. Use "do not" instead of "don't" for formal writing.
2. Replace vague phrases like "some other people" with clearer expressions such as "in extreme cases."
3. Avoid using "hit them" in isolation; specify the action and its context.
4. Use "discard their bodies carelessly" instead of "throw the pet body everywhere" for better clarity and tone.
