Reina  wrote in her blog (博客);“a few months ago I took my cat to the vet(兽医)because she was old and very sick . The vet injected her in the stomach and said she would die .She tried to stand but she couldn't .It took at least twenty minutes for her to die . I sat in the room with her and the vet came in a couple of times and finally he said she was gone . I will never forget how she died .Was she frightened ? What was wrong with the old way ?"

Dear Reina

My beloved cat Bugle was very sick with kidney (肾)failure and I took him to the vet . I stayed with him for 10 minutes , holding him in my arms and loving him as we always did ,and he look at me ,as if to say ,"It's ok ....I'm ready." After that the vet came in and injected him with the shot that would put him into a quiet sleep .All the while I held him and told him I loved him , then the vet said his heart stopped beating .They placed him in a little box and I took him home and buried him in the yard where we always run and played ,right under his favourite bush .I still cry myself to sleep ,even though I  am a grown man of 65 years of age ! That cat means everything to me .I have a little stone on his grave and it says ,"Bugle ,my beloved cat ,you were so smart and loving ,I shall miss you every   day for the rest of my life !"

I am sorry for your loss and I know you must feel.I hope this comforts you some .

Love COL Bright .
