We pick many cats from the street, most of them are abandoned and sociable, so we look for a family for them.
But many of them have borne and lived in the street and they are not happy living in a house or an apartment, perhaps, they cannot stay outside because the obvious inconvenients (constructions, bad people who can poison them.
For these cats we need outdoor places, insurances, some kind of shelter (we can provide the structures) for relocate groups (colonies) of unsociable and healthy cats. When we pick them up, we analyze them, sterilize and vaccinate.
These casts are healthy, they don´t transmit any disease and they don´t reproduce uncontrollably, they only need someone who feed them and a temporary control. The places must be safe, far from the roads, neighbours who can feel annoyed and far from areas where there are a lot of dogs or other potential threats.
In exchange, they can control the possible rodents and entertain you with their games and prank larks.
