Phobos was a big healthy lively and friendly cat until yesterday morning when his back legs suddenly stopped working. Today we took him for a lethal injection. No choice. Saddle thrombus is the worst; neither instantly struck down nor with a lingering illness that we could come to terms with, but his old self from the waist up and dead from the waist down and in agonising pain (until the vet gave him some excellent drugs). We will miss him so much.
