Health - Kitten

Domestic kittens in developed societies are usually vaccinated against common illnesses from two to three months of age. The usual combination vaccination protects against Feline viral rhinotracheitis (FVR), Feline calicivirus (C), and Feline panleukopenia (P). This FVRCP inoculation is usually given at eight, twelve and sixteen weeks, and an inoculation against rabies may also be given at sixteen weeks. Kittens are usually spayed or neutered at approximately seven months of age, but kittens as young as seven weeks may be neutered (if large enough), especially in animal shelters. Such early neutering does not appear to have any long-term health risks to cats, and may even be beneficial in male cats. Kittens are commonly wormed against roundworms from about four weeks.

Schrödinger's cat

Schrödinger's cat is a thought experiment, usually described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The scenario presents a cat that might be alive or dead, depending on an earlier random event. Although the original "experiment" was imaginary, similar principles have been researched and used in practical applications. The Cat paradox is also often featured in theoretical discussions of the interpretation of quantum mechanics. In the course of developing this experiment, Schrödinger coined the term Verschränkung (entanglement).
