Snip-There was no consistent Nazi policy for treatment of Jewish owned pets before the spring of 1942. The question arose quiet often when dealing with the segregation or deportation of Jews, since they owned pets just as commonly as any other group. Most often, Jews were banned from bringing their pets along and had to find foster families for their dogs, cats or birds within a very short time. This was the case, for example, in the uprooting of Jews from the shoreline of the Netherlands in 1941.
As long as the deportation had been announced a few days prior, finding a solution for domestic animals was the responsibility of the owners. But in an event of sudden mass-deportation or sealing of a Jewish neighborhood as a ghetto no time was given for such actions, and the problem thus became very much that of the authorities. In Eastern Europe, for example, Jews sometimes naively brought their pets along to the roundups prior to Einsatzgruppe executions, believing they were being resettled."
