Our story starts around a few months ago when a female cat gave birth to a 4 kittens in our backyard. At the time we didn't know what to do so we called RSPCA and asked them what we should do and they told us "the mother cat will take care of the kittens just leave them alone and they will go away", however my mother didn't want to leave them alone because she thought they would starve and she started buying food for them and the mother.
When the cats started opening their eyes this orange tomcat that walks around our neighbourhood randomly started coming to us and eating the food, at the time we thought nothing of it. However one day he decided to take one of the kittens overnight, (we know he did it because he was trying to accomplish it all day but we kept stopping him). We ended up thinking that he had eaten the kitten and we thought we could do nothing about it. One month later he comes back and starts to do this thing where he goes on top of the mother cat and bites her neck (mating I assume) However the mother cat doesn't allow him to do this and she usually walks away or fights him off.
Fast forward another month and now he is trying to do the same thing with the KITTENS! WHERE HE BITES THEIR NECK AND JUMPS ON THEIR BACK (again I assume this is mating).Roughly about 2 weeks ago he took another one of the kittens overnight however this one ended up coming back on its own. We always shoo him away. Recently the mother cat has stopped spending less time with her kittens and going away more and sometimes doesn't come back for a few nights We all assumed this was to get away from the male tomcat.
This morning he came back and started doing the thing where jumps on their back and starts biting the kittens necks again (one of the kittens has gotten to the point where the fur has started falling off and you can see some of his skin on his neck which is really disturbing and worrying). The mother cat has gotten to the point where she always runs away when she sees the tomcat and doesn't come back for a bit
We are really worried for the kittens and don't want them getting pregnant and having litter at such a young age. You are probably wondering why we haven't just brought the kittens into our house however when we do that they just hide behind the fridge or go into a really dark corner with wires which is really dangerous. What should we do? Is there people we can call to come take the cats away? We live in the UK so if you can give us any UK related homes or something to come take the kittens away. We are worried almost everyday.
