The RSPCA has defended itself after being criticised for fixing the broken teeth of a tiny vole.
The field vole, which weighed around an ounce, was admitted to Stapeley Grange Wildlife Centre with broken incisor teeth.
Vets built an anaesthetic chamber in a cotton bud box, using small dental instruments to even out the teeth to allow the vole to chew food again.
However, the charity faced criticism after it shared pictures of the operation on Facebook, but most congratulated the charity for helping the vole. …
Doctor Bev Panto, the centre’s veterinary officer, said: “The procedure cost nothing. We do not discriminate between different species and care for all animals.
“We believe every animal has the right to an existence and if an animal has a reasonable chance of rehabilitation into the wild then we will give it that chance, regardless of species.”
Dear Kitty. Some blog 
Well done RSPCA, its not the hierarchy that is what matters it is the symbolism of “all great creatures and small” that is of importance.
A lesson that British compassion is a light to the world of animal concern.
