Well, it seems Tiger did not make it. After a few days at the vet he was still not able to move and our neighbours decided to take him out of his misery. I have previously saved 5 other cats, which for some reason like to stroll around our backyards (we have moved a lot) and never quite anticipate how fast Tarzan really is. Tiger was not so lucky, unfortunately. Please, all you cats, stay out of our backyard!
