A shopping tiger is a very useful addition to your shopping expeditions and can often add a completely new dimension to the retail experience. It is remarkable how queues just seem to melt away once you join them with your shopping tiger in tow. Just a simple low growl from the shopping tiger is enough to remind the other members of the queue of that urgent appointment they are in danger of missing if they tarry any longer.
A well-trained shopping tiger will - of course - almost instinctively know to bare its teeth and lunge forward as soon as it hears the phrase 'Can I help you?' Conversely, for those situations when you actually need a shop-droid to perform some task and they are - inevitably - nowhere in sight, the shopping tiger can be sent to hunt one down and drag it back to you (with most limbs in reasonable working order) in a matter of moments, even from those previously inaccessible STAFF ONLY areas.
However, I know that my choice of a nuclear-powered shopping tiger may have raised a few eyebrows amongst those who consider themselves environmentally-aware. I don't think there are many people left who deny that there is such a thing as environmental damage, or climate change. So, such aids to shopping as the coal-driven lion pride, or the gas-turbine leopard are sadly, in this day and age, too environmentally unfriendly for even the shortest shopping expedition beyond buying a morning paper, or maybe a bottle of milk, from the corner shop.
Some environmentalists do advocate the use of, for example, the solar-powered wolf pack, the wind turbine-driven weasel horde, or even the water-wheel-powered hyena (with integral battery-backup) - which has, unfortunately, a very limited range indeed, where even a trip to the off-licence can exhaust its power reserve.
Personally, I strongly believe nuclear powered shopping beasts the only really viable option for a more environmentally-friendly future. This is where, I believe, the nuclear-powered Bengal shopping tiger really comes into its own because the nuclear-powered tiger will - as it is a cat, of course - bury its own waste.
