Usually it is required.

Cedar Rapids Municipal Code  23.02 states “It shall be unlawful for any person to own a cat or dog over 4 months of age which has not been currently vaccinated against rabies in accordance with the Compendium of Animals Rabies Control as compiled by the National Association of State Public Health Veterinarians, Inc.,” and that “every cat or dog over 4 months of age shall wear a collar with a valid rabies vaccination tag attached to the collar when outside the owner's residence. “

似乎沒有州法規定。不知道你住在哪裏一般來說城區會有類似的規定，如果你住在大鄉下可能沒人管。
但是獸醫作為私人營業，可以拒絕接受沒有接種的動物，或者以各種名義拒絕，沒有必要一定為你服務。

任何疫苗都是權衡利弊。如果不打疫苗的結果是你貓貓跑出去被咬最後被強製安樂死，那麽你需要權衡一下打疫苗對貓貓的任何虛幻的“害處”。你是主人自己看著辦。

• 謝謝您的科普，檸檬律師。看來，我最好聽從獸醫的建議。貓是我的主人。 -蘇梅- ♂ (0 bytes) () 02/04/2022 postreply 12:37:26
