I have a ragdoll and he used to be a really loving and loved cuddles etc but suddenly he became really angry and now he hates being touched and runs away whenever i try to stroke him or pick him up and he always growls at me, does anyone know any reasons on why this could be happening?? I did have a cat who passed away suddenly last year and my ragdoll was quite close with her so maybe he misses her but im not sure. if anyone has any idea or advice i would appreciate it!
