Missing cat from Griffin Rath Hall, Maynoot

Hi, has anyone seen my cat? Missing from Griffin Rath Hall, Maynooth. Pashtet (3 yo, male, neutered) was in temporary home while I was not in country and possibly left the house through the open window, he has never been on a street, he is shy and may be hiding somewhere. He needs a special diet and treatment, has a microchip. 0873572946 Ana
