I think so....my present cat is 18 this year and 1/4 siamese...when she's awake, non-stop talking..drives me mad...but I love her.
When she's asleep....twitching...whiskers going...then sometimes...as though she's been disturbed..no-one near her....lets out a horrendous squeal..frightens me to death..so I re-assure her and she just goes back to sleep.
She did,nt make a sound until she was 3yrs even during the day' we thought we had a mute cat. By gawd she's made up for it since!!!!
