I thought that Mr Nearly 16 was on his final slope, so spoke to our vet, who has given up solo practice, and joined a group a long way from us. I was checking if she would still get able to come to our house if needed, or if I would have to take him in.
Just having the conversation seemed to give the old guy a new lease on life, like he knew!
Same as vet asked if I needed any of my horses stand by meds, said he was doing fine, asymptomatic for months. Well next day he needed his meds!
We call it s0ds law
