Thomas Deeny is a graphic designer who specializes in book layout and game design. His layout work can be found in roleplaying games like John Wick Presents' 7th Sea, Atlas Games' Unknown Armies and Over the Edge, MCDM Production's Strongholds and Followers, and Modiphius Entertainment’s Star Trek Adventures. He lives in a house in the middle of a spooky forest at the edge of civilization.
Part of the kitten's immune system is the mucosal immune system, which is within the gastrointestinal tract. The mucosal immune system is largely responsible for coordinating proper immune responses by tolerating innocuous antigens and attacking foreign pathogens.[27] In order to optimize kitten health and increase chances of survival, it is important to optimize the link between the gut-associated lymphoid tissue and the microbiota of the gastrointestinal tract. Lasting health and longevity can be accomplished partly through proper nutrition[28] and establishing a healthy gut from birth through utilizing colostrum.[29]
Here in eight lines Eliot was describing an intensely recognizable character with powerful human resonances, while introducing the themes of mortality, and the past, which occur repeatedly in the major poems. We decided that if Eliot had thought of being serious, touching, almost tragic in his presentation of a feline character, then we had to be doing a show which could contain that material, and the implications of it. Furthermore, we would have to achieve the sense of progression through themes more than incidents.[17]

Kittens require a high-calorie diet that contains more protein than the diet of adult cats.[43] Young orphaned kittens require cat milk every two to four hours, and they need physical stimulation to defecate and urinate.[6] Cat milk replacement is manufactured to feed to young kittens, because cow's milk does not provide all the necessary nutrients.[44] Human-reared kittens tend to be very affectionate with humans as adults and sometimes more dependent on them than kittens reared by their mothers, but they can also show volatile mood swings and aggression.[45] Depending on the age at which they were orphaned and how long they were without their mothers, these kittens may be severely underweight and can have health problems later in life, such as heart conditions. The compromised immune system of orphaned kittens (from lack of antibodies found naturally in the mother's milk) can make them especially susceptible to infections, making antibiotics a necessity.[46]
Purring may have developed as an evolutionary advantage as a signalling mechanism of reassurance between mother cats and nursing kittens. Post-nursing cats often purr as a sign of contentment: when being petted, becoming relaxed,[143][144] or eating. The mechanism by which cats purr is elusive. The cat has no unique anatomical feature that is clearly responsible for the sound.[145] It was until recent times,[when?] believed that only the cats of the Felis genus could purr. However, felids of the genus Panthera (tiger, lion, jaguar, and leopard) also produce non-continuous sounds, called chuffs, similar to purring, but only when exhaling.[146]
Cats started the megamusical phenomenon, establishing Broadway as a global industry and directing its focus to big-budget blockbusters, as well as family- and tourist-friendly shows. Its profound but polarizing influence also reshaped the aesthetic, technology, and marketing of the medium. The musical was adapted into a direct-to-video film in 1998, with a feature film adaptation by Tom Hooper set to follow in 2019.

By 2012, the royalty payments from Cats to the Eliot estate had totaled an estimated $100 million.[294] Valerie Eliot used a portion of this money to establish the literary charity Old Possum's Practical Trust, and to set up the T. S. Eliot Prize which has since become "the most coveted award in poetry".[337][338] Cats also turned things around for the independent British publishing house Faber and Faber. As the publisher of Old Possum's Book of Practical Cats, royalties of up to £1 million annually[316] kept the then-struggling Faber afloat during the 1980s.[339] Moreover, the musical led to a surge in the sales of Eliot's book.[1] The success of Cats led Faber to turn another of their literary properties, Ted Hughes' The Iron Man, into a 1989 musical of the same name.[340]

Cats are similar in anatomy to the other felid species, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. They are predators who are most active at dawn and dusk (crepuscular). Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. Compared to humans, they see better in the dark (they see in near total darkness) and have a better sense of smell, but poorer color vision. Cats, despite being solitary hunters, are a social species. Cat communication includes the use of vocalizations including meowing, purring, trilling, hissing, growling and grunting as well as cat-specific body language.[7] Cats also communicate by secreting and perceiving pheromones.[8]
