Unfortunately things did not go as well as I´d hoped. She said after a couple of days he started scratching incessantly, having caught fleas from the park I´d asked her not to take him to (he hadn´t had fleas for 14 years) and was covered in bites. When I got back from my travels and fetched him he also had a pea-sized weeping hole on his back where he´d had a wart. She said it had looked like a tick. I don´t know if she tried to remove it...all I know is it took me nearly two weeks to heal it. She also managed to get through double the amount of heart medication he takes despite the fact that I had left detailed written instructions on doses and times. Luckily the overdose for three weeks doesn´t seem to have affected him.
All in all although I´m sure she made a great fuss of him and was very affection and well-intentioned, I don´t think I´ll be able to leave him with her again. It´s a pity as I´m running out of options but can´t travel unless I´m sure he is safe and happy with someone trustworthy.
