It's so sad when its a young animal but when we take on pets, I suppose we accept that responsibility. We've had to have two cats put to sleep - although both were very old, so that tempers it a bit. Thankfully, our vet comes to the house so they died in front of their own fire, in their beds. If I had to go to the surgery, they would have to huckle me out the back, wrapped in a blanket to avoid distressing everyone else. I think I'm prepared but I'm not really.
But Tess is grand - grumpy as ever but starting to use the leg - if we remind her! I think she's got used to being on three legs!
