OBJECTIVE To determine reproductive capacity of naturally breeding free-roaming domestic cats and kitten survival rate. DESIGN Prospective cohort and retrospective cross-sectional study. ANIMALS 2,332 female cats brought to a trap-neuter-return clinic for neutering and 71 female cats and 171 kittens comprising 50 litters from a cohort study of feral cats in managed colonies. PROCEDURE Data collected for all cats included pregnancy, lactation, and estrus status and number of fetuses for… 
Demographic differences between urban feeding groups of neutered and sexually intact free-roaming cats following a trap-neuter-return procedure.
TLDR
Targeting the TNR method mainly at feeding groups in urban residential neighbourhoods may result in increased group size, as a consequence of 2 major changes in group dynamics: sexually intact cats immigrate into the neutered groups more readily and neutered cats reduce their emigration rates, possibly because of a reduction in reproductive and competitive pressures.
The Swedish breeding cat: population description, infectious diseases and reproductive performance evaluated by a questionnaire
TLDR
The questionnaire based study gives a combined description of management, infectious diseases and reproductive performance in breeding catteries during 1 year and the percentage of stillborn kittens increased with the age of the queen and litter size, and also differed among breeds.
Reduction of free-roaming cat population requires high-intensity neutering in spatial contiguity to mitigate compensatory effects
TLDR
It is concluded that cat population management by TNR should be performed in high-intensity, continuously, and in geographic contiguity to enable population reduction.
Costs and benefits of trap-neuter-release and euthanasia for removal of urban cats in Oahu, Hawaii.
TLDR
Results of sensitivity analyses suggested trap-neuter-release programs that employ volunteers are still less cost-effective than trap and euthanize Programs that employ paid professionals and that trap-NEuter- release was only effective when the total number of colony cats in an area was below 1000.
Survival, Fecundity, and Movements of Free-Roaming Cats
TLDR
It is suggested that human interactions may result in high, localized free-roaming cat densities, which may concentrate feral cat impacts and should be considered when evaluating population control strategies.
Population characteristics of feral cats admitted to seven trap-neuter-return programs in the United States
TLDR
It is suggested that it is feasible to safely sterilize large numbers of feral cats and that the experiences of existing programs are a consistent source of information upon which to model new TNR programs.
Survival of Feral Cats, Felis catus (Carnivora: Felidae), on Mauna Kea, Hawai'i, Based on Tooth Cementum Lines1
TLDR
This work constructed the age distribution and estimated survival of feral cats in a remote area of Hawai'i Island using cementum lines present in lower canine teeth, and suggests annual cementum line formation.
Implementing Nonlethal Solutions for Free-Roaming Cat Management in a County in the Southeastern United States
TLDR
Three methods of humane, nonlethal management of free-roaming cat populations that were successfully applied in Hillsborough County, Florida are described: low-income spay/neuter vouchers; small- and large-scale trap, neuter, vaccinate, and return (TNVR); and return to field (RTF).
Causes of Death in Stray Cat Colonies of Milan: A Five-Year Report
TLDR
Knowledge of the most common causes of death of colony cats could make an important contribution to the health monitoring of these cats and sanitary control of their habitats and provide information on possible related emerging animal welfare concerns.
Estimating free-roaming cat populations and the effects of one year Trap-Neuter-Return management effort in a highly urban area
Free-roaming cat populations are increasing in urban areas around the world. Management strategies remain controversial, as attempts to rapidly minimize the impact of cats may conflict with finding

Characteristics of free-roaming cats evaluated in a trap-neuter-return program.
TLDR
Neutering programs for free-roaming cats should include preparations to perform more spays than castrations, as Typically, almost half of the female cats trapped during spring will be pregnant and care should be taken to differentiate previous castration from retained testicles.
Reproductive performance in a cat colony over a 10-year period
TLDR
Litter size was smaller for the first litter but then increased to a constant 'plateau' until almost the end of the queen's reproductive life, and kitten mortality was lower in the summer than in the winter.
Ecology of the Feral Cat, Felis catus (L.), in South-Eastern Australia II.* Reproduction
TLDR
F feral cats collected over a 3-y period from south-eastern Australia showed no significant monthly variations in either combined whole testes weight or percentage of seminiferous tubules containing spermatids or spermatozoa, but significant monthly changes in combined epididymides weight indicated a low-intensity reproductive cycle.
Population biology and the control of feral cats on Marion Island.
TLDR
Data obtained through transect surveys before and after suggest a continued decrease in population size since 1977, and the fully susceptible population had been exposed to the host-specific contagious disease feline panleucopaenia during March 1977.
Estrous length, pregnancy rate, gestation and parturition lengths, litter size, and juvenile mortality in the domestic cat.
TLDR
Estrous length in 23 bred cycles was not shorter (p greater than 0.05) than in 15 nonbred cycles, suggesting that induction of ovulation does not decrease estrous length.
Spatial Organisation of Urban Feral Cats (Felis Catus) in Jerusalem.
TLDR
It is suggested that the distribution of food patches, the amount of food available and the rate of food renewal determined the cats' spatial organisation.
Reproductive biology and population characteristics of bobcats (Lynx rufus) in Arkansas.
TLDR
Reproductive tracts were examined from 74 male and 64 female bobcats collected in Arkansas between June 1970 and April 1972 and age structure of the sample suggested a low adult mortality rate.
Population dynamics of San Joaquin kit foxes at the naval petroleum reserves in California
TLDR
Kit fox abundance in the southern San Joaquin Valley is highly dynamic, warranting conservation of sufficient habitat to maintain viable populations of foxes through population lows, and research on management strategies to optimize habitat quality, particularly prey abundance.
A survey of sexual behaviour and reproduction of female cats.
TLDR
Details of reproductive activity among 168 breeding queens were obtained from a survey of specific information supplied by cat breeders, and are considered to illuminate usefully a scantily reported topic.
Morbidity and mortality in neonatal kittens.
TLDR
The mortality patterns of 294 Domestic Shorthair kittens indicated that birth weight was closely related to survivability, and low birth weight kittens tended to survive less often than normal birth weight kitten kittens, even within the same litter.
