This would raise much useful tax for the benefit of us humans. (and/or for pet veterinary charities, RSPCA, RSPB etc).
Any "outcry" about this (as those regarding banning fox-hunting) should be ignored like "babies throwing toys out of their prams".
Licences should be necessary for ownership of dogs, cats and perhaps for noisy roosters and other anti-social cases. Animal licences should be only issued to adults.
This must also apply to guard dogs since some of these are dangerous.
The over-indulgence in the UK of pet soppiness and sentimentality has now gone too far.
Taxes might deterred a few people from becoming owners of a pet or a group thereof. Some wealthy people might continue to own large numbers of dogs and cats and could afford to pay these taxes. Any fewer pets would lessen carbon emissions relating to numerous pets and related pet food production. Pet-food could also have extra VAT incurred?.
Not everybody loves the pets of other people (though to the owners we feel obliged to make a pretence that we do).
Neighbours keep more than one cat at a time which live in and spoil our gardens and plants, with digging and excrement (containing parasites) etc.
Gardeners and people who like to sit or play in a pest free, clean garden can become extremely upset by the owners of numerous cats (and feeders of stray cats).
Nobody can go for a nice country walk without meeting hoards of often large dogs and their trip-hazzard leads. We are obliged to smile at these somewhat addicted persons, pretending that we too love all these annoying creatures with their barking and yapping. We have to say "it doesn't matter" when they jump up on us with their claws and muddy feet, or terrify the sensibly-fearful young children.
Pets of course should be permitted, but like driving the motor car their ownership is surely not a human right without reponsibilities and costs. Excess numbers of pets hold dangers and anti-social problems in our society.
On walks out more people are sociable towards dog-owners than to parents of young children. Not that there is anything wrong with being sociable.
Soppiness about pets is nowadays over the top (such as people saying "it is just nature" when hoards of pet cats wreak death upon all the UK's wild creatures; or who say it is cruel to keep dogs in a kennel or "wrong" to eat dogmeat or horsemeat)
Is it not possible for people to walk about healthily, to admire birds and other wildlife etc, without the dog-dependent owners acting out a scene from "ideal country living" with dogs posing as the essential accessory to this activity?
Cats are responsible for the decrease in our endemic beautiful wildlife. They and dogs cause ill-feeling between neighbours.
Dogs and cats are indeed loveable, intelligent companions, but there is no reason why taxes should not be imposed upon their ownership (as taxes are on most aspects of life).
Money raised could perhaps go to special purposes if wished by pet-owners.
Perhaps certain disabled people and housebound, and special dogs like guide-,sniffer- and a few tru pest control dogs be exempted if it were requested?.
Hounds would, like dangerous guard dogs, also be licenced. They surely cannot be, as labelled, real "working dogs" when just an accessory to ridiculous posh overbearing "country sports". Hunts are as irritating and overbearing as the shooting of those poor specially-bred pheasants for fun. Such shooting and hunts are an impediment to safety and an impediment to family footpath walks of rural residents.
All that pro-hunting tosh spoken about the "real" life in the country does not convince most of the inhabitants thereof.
For many self-contained and self-controled people who actually love animals but do not choose have a pet at that particular time, the pets of others can be extremely annoying and un-neighbourly.
Why is this idea important?
Because this is an ideal tax raising opportunity.
Because too many pets increase global warming, as does pet-food production.
To reduce the amount of excrement left in peoples’ gardens, in parks and on footpaths.
Because our society has become overly sentimental about dogs and cats.
