The Town Hall of Mairena del Alcor has sterilised nearly 80 community cats in its latest CER programme campaign, of which almost half were females, which will curb the growth of the colonies.
The latest campaign of the CER programme (Capture, Sterilisation and Return) in Mairena del Alcor has successfully sterilised around 80 community cats. Of these, nearly half were females, a key figure to reduce future litters and control the feline population in public spaces.
The Town Hall of Mairena del Alcor has detailed that the intervention has taken place in various colonies throughout the municipality, with the collaboration of local coordinators and caregivers. Their involvement, according to municipal sources, is essential for the development of the programme and to ensure the well-being of the animals.
The sterilisation of females will, according to the council, reduce the number of litters expected next autumn. This is hoped to curb the uncontrolled growth of feline colonies, a recurring problem in many towns in the Aljarafe region.
New ordinance to regulate colonies
At the same time, the Town Hall is working on amending the Municipal Ordinance for the Management of Feline Colonies. The aim is to improve the functioning of the CER programme and provide it with a clearer regulatory framework.
Among the main new features, according to the local government, will be the regulation of fixed and non-fixed feeding points. The idea is to achieve a more organised management and prevent uncontrolled points from arising that could compromise the effectiveness of the method.
Although the new ordinance is still in the drafting phase, some measures have already begun to be implemented. All feeding points must be identified and coordinated within the municipal programme. Those of which the Town Hall has no record—either because the caregiver is not registered in the municipal registry or because it has not been communicated by the coordinators—will be removed.
“Any feeding point of which the Town Hall has no record will be removed to avoid uncontrolled points,” warn officials from the council.
Civic collaboration is key
The Town Hall of Mairena del Alcor has called on residents to collaborate in a coordinated manner with the municipal programme. Those wishing to care for community cats must register in the municipal registry and follow the established guidelines.
“The involvement of caregivers is essential, but we also need any new person who wants to help to do so within the programme,” municipal sources state. This way, a responsible management of the colonies and better civic coexistence is guaranteed.
The sterilisation campaign has been well received by local animal welfare groups, who have been calling for more decisive measures for years. With nearly 80 cats sterilised in this latest phase, Mairena del Alcor stands out as one of the most active municipalities in the Los Alcores region in applying the CER method.
For residents, the measure provides relief: fewer litters mean fewer nighttime meows, less disturbance, and, above all, fewer animals wandering the streets in precarious conditions. The new ordinance, once approved, will provide a legal framework for these actions and allow penalties for those who violate the rules.
For now, the Town Hall encourages interested parties to inquire at the municipal registry and join the network of coordinated caregivers. The next sterilisation campaign is scheduled for spring 2027, according to sources from the Animal Welfare department.
