My 23 yrar old cat has one cannine tooth left. He has to have lots of pills for his kidneys. You would be astonished how many times he has bitten my fingers as I tried to give him pills with that one tooth, that is now nearly transparent with age but as sharp as a needle. This product has saved our relationship, other wise I would have got a court injunction on the old devil for biting me. I have just bought a replacement for my old pill giver, which vanished last week, I suspect carried away and hidden behind a cupboard somewhere.
