Hi everyone, I'm new here and was hoping you could help me better understand my cat's behavior. Our cat is now 5 months old. We wanted socialize him although this is rather difficult since 'corona happened', so we started walking him on a leash. It's great, he loves it and isn't frightened of people at all. However when it comes to animals, his behavior is rather strange and I was hoping some of you could help me understand him better. Our neighbors have a cat as well, so we tried introducing them. At first both at the other side of a window multiple times, then in the garden, both on a leash but we didn't let them get too close. This all went well. Now in the next stage, my cat always does this: he seems really relaxed and playful, he always does his best to get as close as he can to the other cat, but when he finally is close, it looks like he becomes extremely frightened: flat ears, pupils dilated, his hairs are raised, back curved, sometimes he hisses... Even though I don't see any aggressive behaviour from the other cat...This happened already 3 times now. What did we do wrong? And why does he approach the other cat in such a relaxed manner, when he, in the end, becomes frightened every time (could it be aggression)? Should we give up? (English isn't my mother language, so my apologies in advance for any mistakes!) Thanks!
