In the past two years, convictions secured by the charity have increased from 2,579 to 3,114. Last year, spinster Georgina Langley, 67, of West Hougham, Kent, was raided at her home by the RSPCA and had five of her 13 cats put down.
The charity prosecuted her for neglect, but Mr Smith, 62, came to her aid. After sending two of the cats’ bodies to the Royal Veterinary College (RVC) for an independent post-mortem, he said: ‘There appears to be no good reason why the RSPCA allowed these animals to be put to sleep.
‘The RVC post-mortems concluded the cats were healthy, with no signs of incorrect feeding or major problems with fleas or other illnesses.
‘They were very heavy-handed with an elderly lady and kept her standing out in her garden in the rain for hours while they searched her house.
Following a three-day trial in May 2012, the RSPCA dropped 11 of the 13 charges against Miss Langley.
