EXPLANATORY NOTE 
The proliferation of stray animals, particularly dogs and cats, poses significant public health 
and safety concerns nationwide. Stray animals are potential carriers of rabies and other zoonotic 
diseases, and they may also cause traffic accidents, property damage, and in some cases, personal 
injury. Moreover, these animals are vulnerable to neglect, abuse, and inhumane treatment. 
Local government units have made varying efforts to address the issue of stray animals; 
however, the lack of a uniform, sustainable, and humane program has hindered the development 
of long-term solutions. Cebu City’s Ordinance No. 2526, known as the Compulsory Neutering, 
Vaccination, and Registration (CNVR) of Stray Animals Ordinance, provides a progressive model 
by requiring neutering, vaccination, and registration of stray animals prior to adoption, rehoming, 
or release. This model has successfully reduced stray animal populations and promoted responsible 
pet ownership in its jurisdiction. 
This proposed measure seeks to institutionalize, at the national level, a similar framework to 
control the stray animal population in a humane and scientifically sound manner. Through 
compulsory neutering, vaccination, and registration, the State can help prevent the spread of deadly 
diseases such as rabies, protect communities from the dangers posed by uncontrolled stray animals, 
and uphold animal welfare standards as mandated by existing laws, including the Animal Welfare 
Act (Republic Act No. 8485, as amended). 
The bill further provides funding and mandates inter-agency collaboration among the 
Department of Agriculture, the Department of Health, the Department of the Interior and Local 
Government, and local government units, to ensure effective and coordinated implementation 
nationwide. 
The passage of this measure is earnestly sought in order to safeguard public health, uphold 
animal welfare, and foster a culture of responsible pet ownership throughout the country.
