Hi everyone, new here! My fiancé and I recently moved to Washington state with her cat, Monty. Monty previously lived with one other cat that was a family pet and we decided to get another cat when we moved here to keep her company. To describe Monty, she is a 9 year old calico and my fiancé has had her for 4 years. She is very shy and easily startled. She likes hiding in cabinets and closed confined spaces and spends most of her day sleeping. She likes to be pet often. However, she does not like to play at all with humans and only occasionally plays by herself. She also is quite particular about where she sleeps and can be a picky eater. Now to introduce our new cat, Maze. Maze is a 6 month old black cat. She is full of energy and is extremely playful. Loves climbing, jumping, and also loves being pet. It has been two days since we got her and she is still settling in. We have had some occasional excessive meowing but I assume it is because she is still anxious about the move? We have formed a plan for the introduction and plan on giving it some more time, but needless to say the two cats are not getting along quite yet. We put Maze in the bathroom and have established our office as her play area. When sleeping we return her to the bathroom and when we leave, we also return her to the bathroom. The first day we decided to bring them to the door and tried to limit physical vision of each other as much as possible. Unfortunately (but expected) Monty hissed from under the door and at Maze through the crack. We let them sit at the door for awhile before decided to end the ‘session’. On day 2 we kept them away from each other all day while spending time with them separately. While Maze was locked up in the bathroom, Monty decided to wander into the office and shortly came out after. We decided to have them eat on opposite sides of the door this evening and it did not go well. Monty loves to eat and wouldnt eat her food until we moved it further back from the door. She ended up eating most of her food and Maze was just chowing down. Monty hissed a few times at her from the other side of the door. However, Maze wanted to play with a toy on the other side and she stuck her paw under the door which Monty subsequently lunged, swatted , and hissed at her paw. Now that everyone is up to date on this- I wanted to ask for advice going forward. (Also apologize for the long post). We were planning on maybe buying a dog gate and adding a visual factor by Tuesday. Thoughts and criticisms?? Thanks everyone!!
