Hey everyone. I just adopted another kitten and she is about 3-4 months old. My resident cat is about 8 months old. I made a mistake as putting the new kitten to the older one, the kitten was just curious about the room and didnt mind my cat but my older cat kept hissing and growling at her.She would even hiss when she smelled my hands after I petted the kitten. But she didnt chase or attack her. Now I keep them in seperate rooms. Today I put my resident cat in the new cats room after I took the kitten out. I tried to make her play and she kept playing after a bit hesitation and only growled shortly at the smell. Do you think that could be a progression? Would doing this help her get used to new kitten's smell? I really hope they can get used to each other and be friends.
