We put down our cat this weekend Sat. We had him for about 10 years with our other cat that is still with us that we've had for 12 years. He had lymphoma and got too weak so we ended his suffering. My question is about the cat that we still have - his behavior the last couple of days around our dog. We've had our dog with the cats for 5 years. This cat was never really fond of the dog but has gotten close to the dog before and would sniff or head butt him when they're both by me or my husband. Yesterday I was sitting on the couch dog laying beside me and petting the cat on my lap. The cat then bit the dogs snout. I yelled at him and the cat ran away. Tonight the same thing happened but before I could say or do anything the dog growled back and the cat ran away. This hasn't happened before that we know of. Could it be because the cat is grieving or the cat is protecting me or trying to dominate the dog? Not sure what to think. Well just have to keep an eye in them. Anyone else experience this or have any suggestions? Thanks!
