Friends had called police, etc and had taken care of the body and the animals... so far, so good.  

In which case the mouse may have just "passed on through"  by now,  is dead in the snow,  you'll find it's little desiccated body after the thaw.

ThiEnsure that any modifications for disability access they make with your permission are reversible and they agree to reverse these modifications at their expense and not leave you your property with rails and other modifications which an able bodied person will not want in their home if you need to find a new tenant in the future and ensure that all reversal of modifications are done in a professional manor and you are not left with silicone preventing windows from closing or anything else for that matter.You should have everything documented and signed by tenant or the legal carer .
