We have had a numbers of elderly cats brought into the shelter in recent months as they appeared to be a stray or lost, when actually they had a home not far away.
If you have an elderly cat, please do not let them outside unsupervised as they can wander off and get confused and lost. They are also extremely vulnerable.
Let them have a potter in the garden if you are out there with them, but then take them back inside with you.
You want your cat to be happy and enjoy however much longer they have to live, without worrying about what has happened to them when he or she doesn’t come home for tea.
