Dear Weiner,

      I think the government should pass a 1aw to stop people from letting their cats run free. There are three

important reasons why you should do it:

     When cats run free, they hide themselves under bird feeders (喂食器) and kill defenseless (毫无防备的)

songbirds. Every time I put up a bird feeder, I find at least one dead bird in my yard. I'm sure all those birds

were killed by cats. And cats don't even eat the birds they kill. Songbirds belong in our parks and gardens, but

cats don't. Dogs never kill poor little birds. I don't know why people don't want a dog in the first place.

     Cats are always using my garden as a litter-box. This is very dirty and makes me feel sick. Children can't

play in the garden when cats have been there. Dogs are usually tied to trees, so they don't cause such trouble.

Cats spread diseases when they use a garden as a litter-box, so I think this should be stopped.

      Finally, letting cats run free is not even good for the cats. Sure, most cats want to go outside. Their

owners like to give them everything they want, just like spoiled children. But cats that stay indoors live much

longer than cats that run free. Cats are always getting hit by cars when they're allowed to run free.

     I'm sure that if you think about all the things I've said, you will work to pass a law stopping cats from

running free. This will improve our environment, make our parks and gardens cleaner, and even help the cats

themselves by making them live. 

     Thank you for your attention to my suggestion.

                                                                                                                                                  Sincerely,

                                                                                                                                         Eve Harringford
