Hello, I am new here Around the end of April a lovely tabby cat started to sleep on our front door mat and back garden as if it was claiming us. For some time we let it stay in our shed as we have an old ginger (male) tom (also a stray) who wouldn't have taken to another cat in the house. Gradually it won us over and we let it in the house. We found it to be clean and it stayed away from our cat. In fact, it showed submission to him and he often gave it a whack to let it know who was boss. Since then it has started to become dominant and the ginger cat has become nervy and runs away if it even looks at him. Sometimes they play but as ginger (thats his name) is old he just wants a bit of peace and quiet. He has also started to lose weight and spends most of the time hidden away under the bed. They sometimes sleep next to each other and there is no problem but there are moments when the tabby seems to be stalking him all the time. We could put this down to the fact that he is much younger and just wants to play. We also wormed ginger as he was being sick and messing in the same spot on the bathroom (something he used to do) and he has perked up a bit. The other problem is the tabby has been leaving urine marks around the skirting boards in every room, I know it isn't ginger because he doesn't do that as he was spayed. I also caught the tabby in the act once against the log basket. We put it down to a one off but I have since found more evidence. We do not know the exact sex of the tabby but we are pretty sure it is a female. If anyone can suggest what the problem may be I would be and how to tackle it very grateful. We have looked in the local papers and notices in the shop and have not found any missing tabby posts. We haven't taken it to the vet to see if its chipped. Perhaps we should. Thanks.
