I've wondered this for years
Mine have always driven me mad for different reasons, wouldn't be without them though 😹
Dcat1 (deceased) hated everyone except for me.
Dcat2 (deceased) loved everyone but brought me lizards, snakes and spiders 
Dcat3 - has a fetish for sweaty clothes
Dcat4 - goofy as anything, regularly confused by life
Dcat5 - velcro cat
Dcat6 - little rescue nutcase who took over my house last year and DGAF about the rulez 
Please reassure me I'm not alone 😅
