It is certainly possible to help our elderly cat to recover a good routine, in fact there are few tips that, if put into practice, give this elegant animal all the balance and autonomy that distinguishes it again:
stimulate him to play, buying mice to load and hiding delicious treats in order to stimulate his nature as a hunter.
Never let him isolate himself, so always involve him in family activities, frequently calling him to stay close to the bosses during everyday tasks.
Clipping his hair to improve its condition and to optimize the hygienic conditions of its coat. Wash it with a wet wipe without neglecting the anal and genital area.
