Methods, systems, and/or devices for thermal treatments

A soaking-device that comprises:

• a wettable-floor-and-sidewalls that forms both a wettable-floor and wettable-sidewalls of a wettable-subassembly of the soaking-device, wherein the wettable-subassembly is configured to hold a volume of an immersion-liquid without leaking;
• a front-panel that attaches to a first terminal-end of the wettable-floor-and-sidewalls;
• a rear-panel that attaches to a second terminal-end of the wettable-floor-and-sidewalls, wherein the wettable-subassembly comprises the wettable-floor-and-sidewalls, the front-panel, and the rear-panel, wherein when the front-panel is attached to the wettable-floor-and-sidewalls and the rear-panel is attached to the wettable-floor-and-sidewalls, then the wettable-subassembly is formed;
• and
• an outermost-shell that forms both an external bottom and an external sidewalls of the soaking-device, wherein the outermost-shell externally covers over the wettable-floor-and-sidewalls;
• wherein the wettable-subassembly when holding the volume of the immersion-liquid is configured to soak a portion of a body part of an animal.
