請重視犬貓絕育的重要性。我看過八個月大就子宮蓄膿的母貓；塔克早在剛滿五個月、不曾發情的時候就結紮了，現在七歲身體健康。
常聽說的「發情後再紮」、「兩歲後再紮」、「生過一胎之後再紮」、「反正不出門所以不用紮」，甚至是「公貓在發情前結紮會使尿道太窄而容易尿結石」……這些都是沒有根據的說法！公貓的蛋蛋和尿道的寬窄沒有關係，在食物中給予足夠的水分，才是預防尿道結石的根本方式。
更何況，等到貓咪已經出現發情噴尿、嚎叫、逃家的行為之後再結紮，難保未來不會再有。（不是恐嚇，系金A柳～）
照片裡是一隻約四歲的母犬，前一陣子因為子宮蓄膿來結紮，這一陣子因為乳腺腫瘤來切除，而且才切一邊，您看，您忍心毛孩子經歷這樣的大手術嗎?請結紮您的寵物伴侶。
Why Spay or Neuter?為什麼要結紮?
If you think that just having one or two litters won't hurt anybody, this fact should change your mind: according to the Humane Society of the United States, 10,000 babies are born in the U.S. on any given day. On that same day, however, 70,000 puppies and kittens are born. Match those two statistics up, and you'll see that there will never be enough homes for all the animals born in this country unless we all take responsibility for spaying and neutering our pets. Change begins with YOU! Spay or neuter your pet!
如果您覺得讓您的寵物伴侶生個一胎二胎的無傷大雅，那請您看看下面的數據，這可能會改變您的觀念。根據美國人道組織所提供的資料，美國境內在任何一天有約10,000個新生寶寶出生，但在這些新生寶寶出生的同一時間裡有70,000新生小貓小狗。看看這二個數字的對比，難怪有這麼多的新生貓狗找不到家。而要改變流浪動物的衍生，改變就得從"你"開始，身為飼主，請負起責任，結紮您的寵物伴侶。
