:help:I thought maybe there were some cat people on here that also have GSD's that can help me. Last night I came home from work and went to pet the cat and he grabed my hand with his claws and bit into my hand very hard. I had to pry off his claws with my other hand. This was a terrible bite and is really sore today. I can't believe my otherwise friendly cat attacked me like that. This has never happened before, but I am still in disbelief. Anyone have any ideas why a normally friendly cat would do this.
