18 Pa. C.S. § 5553
Where a violation of this subchapter is alleged, an issuing authority may, in compliance with the applicable provisions of the Pennsylvania Rules of Criminal Procedure, issue to a police officer or an agent of a society or association for the prevention of cruelty to animals duly incorporated under the laws of this Commonwealth a search warrant authorizing the search of a building or an enclosure in which a violation of this subchapter is occurring or has occurred and authorizing the seizure of evidence of the violation, including, but not limited to, the animals which were the subject of the violation. Where an animal seized is found to be neglected or starving, the police officer or agent is authorized to provide the care that is reasonably necessary and, where any animal seized is found to be disabled, injured or diseased beyond reasonable hope of recovery, the police officer or agent is authorized to provide for the humane destruction of the animal. The cost of the keeping, care and destruction of the animal shall be paid by the owner of the animal, and claims for the costs shall constitute a lien upon the animal. In addition to any other penalty provided by law, the authority imposing sentence upon a conviction for a violation of this subchapter may require that the owner pay the cost of the keeping, care and destruction of the animal. No search warrant shall be issued based upon an alleged violation of this subchapter which authorizes a police officer or agent or other person to enter upon or search premises where scientific research work is being conducted by or under the supervision of graduates of duly accredited scientific schools or where biological products are being produced for the care or prevention of disease.
