Friends,enemies,or animals that tolorate each other,but don’t exactly like each other?

Our cats,Snowy & Dede are a mystery.When Snowy first joined our household,he wanted to play with Dede,but Dede,old as she is,didn’t want to wrestle around,and when Snowy found out,he just attacked her in a bully type of way.Later,they just accepted the fact that they were stuck with each other,and Dede hissed less,& Snowy attacked less.Now,I’ve seen change in their behavior.Like,I saw Snowy letting Dede drink the water I gave them first,or just today,when they were cuddling together.Maybe soon, they’ll officially like each other!Who knows?
