Diet and Hunting:

Cats are obligate carnivores, meaning they require a diet rich in protein from animal sources to survive. Their diet and hunting behavior are adapted to exploit small prey, such as rodents, birds, and other small animals.

Diet:

Primary sources:
  •  Meat (muscle tissue, organs, and bones)
  •  Fish and seafood (for coastal and aquatic species)
Secondary sources:
  • Eggs
  • Insects
  • Fruits and vegetation (in small amounts)

Hunting behavior:

  • Reptiles and amphibians
  • Fish and seafood (for coastal and aquatic species)

Hunting frequency and success:

  • Frequency: Cats hunt regularly, with some species hunting daily.
  • Success rate: Varies depending on the species, terrain, and prey availability.
Overall, cats are skilled predators adapted to exploit small prey, and their diet and hunting behavior are essential to their survival and success.


Reproduction and Lifespan:

Cats are prolific breeders, and their reproductive cycle is designed to ensure the survival of their species.

_Reproductive Cycle:

  • Female cats (queens) reach sexual maturity at 6-12 months.
  • Males (toms) reach sexual maturity at 12-18 months.
  • Queens are polyestrous, meaning they can breed multiple times per year.
  • The breeding season (mating season) typically occurs in spring and summer.
  • Queens are pregnant for approximately 63-65 days (gestation period).
  • Litter size ranges from 1-8 kittens, with an average of 3-5.

_Life Span:

  • Average life span: 12-15 years.
  • Indoor cats: 15-20 years.
  • Outdoor cats: 5-10 years (due to exposure to disease, injury, and predators).

Kitten Development:

  • Newborn kittens are blind, deaf, and helpless.
  • Eyes open at 7-10 days.
  • Ears open at 10-14 days.
  • Kittens begin to wean at 4-6 weeks.
  • Kittens reach sexual maturity at 6-12 months.

Heat Cycle:

  • Queens typically go into heat (estrus) every 2-3 weeks during the breeding season.
  •  Heat lasts for 4-7 days.
  • Queens will mate with multiple males during this time.

Pregnancy and Birth:

  • Queens will often hide and prepare a nesting site before giving birth.
  • Kittens are born blind and helpless.
  • Queens will care for the kittens, nursing and grooming them.
Overall, cats have a remarkable reproductive cycle, and their ability to breed and produce offspring is essential to their survival as a species.

Vaccinations:

  • Kittens: Receive a series of vaccinations starting at 6-8 weeks, boostered every 3-4 weeks until 16-17 weeks old.

Dental Care:

  • Regular brushing and dental exams to prevent tartar buildup, gum disease, and tooth loss.

Parasite Control:

  • Flea, tick, and heartworm prevention through medication, collars, or topical treatments.

Nutrition:

  • High-quality commercial food or balanced homemade diets, fresh water, with regular monitoring of weight and health.
