Confused on how to handle this

My husband and I have been married for 14 years. For most of it he was in the military and gone a lot. Now that he is out we moved back home and I got pregnant, so we are staying with his Father-In-Law for now. Most of the time it is fine and easier on everyone. I have 4 cats, all older and only one is not declawed. The rest were declawed when I got them. My father in law has stated on numerous occasions that if any cat scratched my now 10 month old daughter he will kill it. He has said this about his ex-wife's new kitten as well. Neither have come close enough to scratched her yet and have always moved away from her. He constantly talks about how he has done it before. His ex has talked about this incident as well. My husband never voices an opinion about this and let his talk this way. I am an animal lover and it breaks my heart when he says this. I have tried to ask him to stop numerous times and he refuses to. He will always turn things around so it is my fault or makes me feel like a bad mother. I love my daughter and would never let either cat harm her and I always keep an eye on them. I am started to resent my husband for not saying anything and it is becoming an issue between us. Declawing her will stop some comments but I don't think it will stop all of them. Part of the issue is I have very little trust of people who hurt animals and talk about doing so repeatedly. I don't know how to get my husband to listen or to get my father-in-law to let us handle the situation as parents.

Thank you for the reply. A cat his family owned years ago did scratch his oldest daughter when he did it. He may have had other bad experiences. I will try and keep this in mind. I know he also just hates animals to begin with. Out cat is an indoor cat she only claws up the leg of a cheap table we bought years ago and doesn't touch any of the other furniture. My father in law has expensive furniture and wooden floors and she has never touched it, amazingly. I have stated numerous time that my daughter comes first and I will never allow anything to happen to her. I have worried about them lashing out due to jealousy. I try and set time aside for them only while my husband plays with my daughter when he gets home from work. My husband did always do what his father says due to his upbringing and the military. My father did the same to me, but one day he started demanding too much and so I had to stand up to him. I am just worried that it will become a situation that my father in laws opinions will be taken into account and mine ignored regarding our daughter. No the cats are not allowed in the baby room. When we brought her home we slowly introduced them. We did have her sleep in our room at first and left the door open for the cats. They learned the boundaries pretty quickly. We taught them not to jump into the bassinet weeks before she was born.
