Not worthy of working with any animals

I took my 13 year old senior girl for a check up. She was diagnosed with early stage 1 kidney failure in October 2021 she was given a special diet. In March 2022 I went to George Animal Hospital as my previous vet by another practice left. I asked for a kidney function test again and this time my girls kidney function was back to normal! I insisted that the injections that she had been getting by the previous vet continue, but the vet said that if I use Metacam then studies has shown that Metacam improves kidney functions. Obviously I trusted him and started giving my girl Metacam thinking wow I'm helping her. 2 Months later my girl was not well and I took her in on the 13th of May and insisted on a kidney test I was told its not necessary as in March everything was fine, but I had a gut feeling... My girl was in complete kidney failure. I HAVE READ AND CONSULTED MANY PROFESSIONALS... EVENS THE MANUFACTURERS OF METACAM SAYS METACAM IS NOT MADE TO GIVE TO CATS AND SHOULD DEFINITELY NOT BE GIVEN TO CATS WITH ANY FORM OF KIDNEY PROBLEMS (PAST AND PRESENT) your ********* lack of knowledge and wanting to play God over my pet has led to me loosing my girl that I have gone through alot and was my companion for 13 years.
