So, my family and I are going on vacation next weekend and we have been preparing my 5 an a half month old kitten Pepper, stay at a friends house for the weekend. Today I brought her over to my friends for the second time to see how she was with my friends cat and dog, after not seeing them for a month. We decided to leave them alone and go out for lunch. When we came back my cat was hiding behind her furnace. When I picked her up she freaked and clawed my neck and hissed/yelled at me. So I promptly took her home. 8 hours after the incident, she now won't come near me and if I try and pick her up she hisses at me. Is she mad at me? Will it last? (She's fine with my brother)
