The higher
cat densities observed near some developed areas may be spillover from overcrowded conditions associated with TNR colonies and unsterilized pets, which may affect native prey populations in areas immediately adjacent to colonies.
Human - inhabited areas and known TNR (trap - neuter - release) colonies are shown because of the higher
cat densities observed near those areas.
Not exact matches
So, although
densities «reaching up to 1,580
cats per square kilometer in urban areas» were
observed, more than half fell between 132 and 417
cats per square kilometer (or 51 — 161
cats per square mile).
It's difficult enough to show a direct link between
observed predation and population impacts; suggesting a causal connection between high
cat densities and declining bird populations is misleading and irresponsible.
