My 16 yr old male cat has gone missing.
To give a brief background he's always been a bit 'dim' and has lots of health problems (hyperthyroidism, arthritis, deaf etc). We moved house 2 years ago and he's never really gone far away, and over the past couple of months has been almost housebound - by his own choice.
I've ring all local vets and rescue centres, he's microchipped, and I've put details on local Facebook pages.
He went out Friday evening, and hasn't come back. How long would you wait before assuming the worst?
