Concerns
Hi everyone
so i have a question for the community. we have two Mainecoons (brother and sister) who are now 10 years old. Over the past 3 weeks the Male (Loki) has started hissing at this sister (Willow) randomly, like hes in the lounge chilling and she walks into the room or past time and he hisses at her. no swiping, just a hiss and then goes back to chilling. my partner and i are concerned about this sudden behaviour change, google says it could be a medical issue of some sort but its not all the time, like they'll sleep next to each other and theres no problem. we moved house last september and they both settled in within the first day so its not a territory thing.
so just looking to see if anyone else on here has experienced this sort of thing?
cheers in advance
