There's a new rehabber/rescuer guy in Texas whose charm and aggressiveness have made him well-known with many, many pet stores in the state. Apparentely he has recently gotten substantial help from Petco. They have not only implemented many of his husbandry changes and reffered many potential adopters to him but they recentely contributed hundrends of dollars worth of supplies and are talking about a cash contribution.
On the other hand i know of a few that i would still like to see closed (or burned). So i think it does depend upon the regional manager.
