I wish , that I could help , aseven at The Found Cats , Princess and Precious , just do not like each other , and when you hear GROWL , HISS AND SPIT! , then 90 % of the time , it is those Two. In some cases , rehoming is the only chioce! Maybe , try seperate rooms , to see if they miss each other. Best of Luck, from the Found Cats Hotel!
