I think I have found the answer
There was a livestock of mice in a experiment flying in Apollo 17. Noticed that when listening to a talk by Daniel Marin, which is an expert in Astronautics
Further search in Gooogle lead to the paper THE APOLLO 17 POCKET MOUSE EXPERIMENT (BIOCORE)
https://history.nasa.gov/SP-368/s4ch4.htmThe paper contains all the details of this experiment, including pictures of the Canister container
https://history.nasa.gov/SP-368/p385a.htmThere is also a reference to the mice experiment during the TV interview to the crew while returning to earth
This are the comments and time:
284:29:38 Mission Control And also, Ron, did the squeaking of those mice onboard keep you awake?
284:29:48 Evans No, the mice really didn't - there are plenty of other things going on inside the spacecraft here that we can hardly even hear the mice. As a matter of fact I really haven't heard them yet.So, seems that this experiment is the box that the crew gives to the swimmers previous to exit the command module
The paper describes the recovery and what they found. It is interesting to consider that the mice container had to survive
the EVA and command module depresurization
Upon arrival at Pago Pago the flight package was taken to a laboratory at the Lyndon B. Johnson Tropical Medical Center. On opening the canister about seven hours after splashdown, four of the five mice were found alive, while the fifth (A-3352) was dead. Two of the surviving mice (A-3305 and A-3356) were active and in excellent condition when released from their tubes into a container for observation. The other two surviving mice (A-3326 and A-3400), when first examined, were docile and hunched up, as though exhausted or arousing from torpor. They moved forward only a few steps when prodded.This confirms again that all is published out there. You just need to investigate and work a little
Best regards
