hey everyone my names justin and im in need of help. Me and my girlfriend are afraid we are way in over our heads. We have a cat that is 1 1/2 yrs old and we just moved out of town and at the same time our friends took in a stray mom and her 3 kittens so we decided to take the female to help them out and save the kitten and we thought hopefully give a friend to our cat. we brought both the cats to the new apartment today, We have the kitten in the bathroom with all her essentials, and for the most part she hides from us, and the time that our cat did see the kitten she hated her, she never hissed before but she was hissing like crazy. the house that we moved out of had an older male cat about 6 yrs old about 20 lbs and they never had a problem. well sorry for the long story but i just need some advice please !!!!
