It turns out that Schrödinger's cat was alive and well, but just lost. When the box was opened there was no sign of a dead cat. However, it has been impossible to find the original (presumably live) one either. Fermat asserted that it was impossible for any cat to exist in a cube-shaped box or a box of any shape and of any number of dimensions other that a flat one with zero volume and claimed to have a discovered a proof of this, although 'there wasn't enough space to write it down', even though there was (or had been) apparently sufficient room for a cat, even if not sufficient room to swing one. Some have nicknamed it 'Fermat's Lost Cat', and there is ongoing debate whether a lost cat is the same thing as a missing cat or a dead cat, and whether a missing cat can be counted as alive or dead.
It was just the same when the new owner of the box, Sir Keir Starmer, opened it and claimed that, as promised, the cat was indeed in there, but very, very small - so small as to be invisible and just about undetectable, and might indeed. actually be dead, or at least broken.
'The cat would need to be much larger if it is to be found, and its state of health determined. So clearly, the answer is that what is essential for this, now, is growth.'
