If you are suspicious the cat you are seeing is feral and are concerned, you can contact the cats protection for more information.
How to find their parents?
If you don’t manage to find any information on their collar and they sadly don’t have a microchip, you can consider putting posters of them around the local area. Word of mouth can be an amazing tool in these instances and if the cat is local, there is a good chance you can get them home.
Social media is also a useful tool, so consider making a post on there. Some of these posts get shared tens of thousands of times and they really help animals get reunited with their loving families.
What if the cat is injured?
If you find a cat that is sadly sick or injured you should contact your local vet or call the RSPCA straight away.. Be very careful when approaching sick and injured cats as they may scratch or bite if they are in pain. Using a soft blanket to pick them up can help stop you getting hurt. If you have a pet carrier you can take them in this, if not, find a nice sturdy box with plenty of air holes.
