The University of Edinburgh has recently backed up its research which has shown that half of all cats over 15 suffer from dementia. The main reason is believed to be better feline medicine and the treatment of conditions like diabetes or liver failure. This is combined with better nutrition and care at home and means that cats can live with dementia. The signs are similar to those in humans including difficulty in settling, blank staring, failing to recognise members of the family, incontinence and getting lost and confused in familiar surroundings. Some treatment may help if the problem is spotted early enough.
