My boy cat keeps fighting my girl cat
They're brother and sister, we got them at the same time. They're both 10 months. I do know and understand that play fighting is absolutely normal and healthy, however the boy is much more into fighting these days and sometimes the girl hisses at him and yowls and squeaks. I just want to know if she's getting hurt and I should get some calming remedies from the pet store or separate them for a bit or something
