If you are in the area, wander in and look around, go talk to them about your cat and fees for services, etc. when you are not on a shop. One location here the space is small enough that even with poor eyesight you could probably read name tags and if you interacted when not on a shop and got the info, returning on a shop at about the same time of day would probably yield the same cast of characters. Another location just opened near me and I don't think the job would be feasible at all.
