Display the posters only where you have permission to do so such as vets, shops, post offices, etc. We do not advise putting up posters elsewhere unless you receive permission from your local council first as it may be a fineable offence. Rehoming a stray cat If you have taken all of the above steps and are unable to find the stray cat's owner within a reasonable period of time, ie 10 days, so long as you can show that all the above steps have been taken, you can then go about finding a loving new home for the cat. If you are unable to keep the cat, please contact your local RSPCA animal centre to see if they can help you rehome it. You can find your nearest RSPCA by using our search facility . Taking on a stray cat If you decide to keep a stray cat , please do ensure that you carefully consider the commitment required. You must be able to provide proper care, accommodation, food and veterinary care for the rest of the cat's life. We would also recommend taking out pet insurance to cover any future expensive vet bills.
