A little over a week ago my boyfriend and I adopted a cat who is four years old. We already had a very mellow and good-natured 9 year old German Shepherd who has been around cats. Initially,the two were separated (for about 2 days) but the cat found its way into the living room and refuses to be kept separate anymore. The dog and cat ignored each other initially and co-existed peacefully. However in the past three days the cat has been hissing and clawing at the dog. My boyfriend and I are afraid that the dog will get hurt and lash out at the cat. We don't want either of them getting hurt. As it is, I was scratched in the face trying to keep the cat away last night. We use the water bottle trick and it is effective, but not always handy. We are open to any suggestions or comments. Where do we go from here? Can anyone reccommend tricks or resources? We don't need the animals to be friends necesaarily, but we want a safe and peaceful home for both of our animals. HELP!!!
