This lady emailed - she's at her wit's end. She has an older cat (10 years old) and two younger cats, and the older cat is suddenly being viciously attacked by the younger two. She said that there was always a certain amount of bullying but that it's become much worse only in the last year (they've lived together for five years). The last attack saw her older cat attacked so badly, he almost died.
She has been to see several vets, but unfortunately while one did prescribe her some medication, it didn't seem to work. A lot of the medication takes a bit of time to see which fit your cat though, and also it often has to be hand in hand with some form of behavioural modification. Unfortunately, there aren't any behavioural therapists in Singapore - I know of a LOT of people with cats who have the same problem (though not so severe fortunately). This poor lady is really very stressed out - she doesn't want to give up any of her cats, but according to her, the vet said any more attacks and her oldest cat is going to be killed one of these days.
If I ever leave the Society one day, I'm going to seriously consider getting trained as a therapist!
