I find it horrific that you have to have 111 rabbits, and that P@H have plenty for sale. Horrific. Its wonderful that you do it (are you the RSPCA?), but horrific that its needed.
We need to get the government to formulate a national rabbit strategy.
I suggest a campaign of public information (Nationally, there are more rabbits than there are people to care for them properly. The kind of care rabbits need. And...)
Rabbit Registration Day. Everyone with care of rabbits should on a particular day, register their charges. Name, description, and neuter-status. Register online, at designated vets/pet shops, or by letter. No excuses. A Rabbit Census.
Rabbit Keepers Licences thereafter issued, for the rabbits you have on that day and no others.
A total ban on buying and selling of, or breeding rabbits and importing of rabbits. Even show rabbits. For a year.
Thereafter, Rabbit Breeders Licences to be available, for a high fee, after mandatory training.
Meanwhile Rabbit Keepers training to be available, at your own expense.
Legislation that people are not to acquire rabbits without first being trained in their care.
Rabbit sales/change of ownership to be allowed, between accredited persons (ie, those who have taken training and can prove it).
Tax on rabbit sales and exchanges. This system has to fund itself. So taxes on showing, too, and on breeding.
Fines for anyone keeping, breeding, exchanging, purchasing a rabbit without the requisite training.
Rabbits to become rare, but well-cared-for pets/companions.
