i live on 2nd floor apt, next to a tree that has a limb about 6ft from my balcony. neighbors cat is unfixed male. i have 2 cats, both fixed, black shorthair female, and sealpoint siamese male that does not see good....my neighbors cat keeps climbing the tree, and leaping to my balcony. i dont see how he can do it , but he does.. i have my balcony door cracked at night so my cats can go out on balcony at night..my neighbor leaves he cat out all night sometimes, and this is when it happens mostly. i put a plant in the corner of balcony to stop this, but he is able to still jump on balcony. i have asked my apt manager to cut the limbs off tree, and then i hear nothing about it...i have had $1200 of vet bills because of this...i am not sure what to do?
