I have 10 year old male cat. Since he came to me as a three months old kitten, he's always been a very nervous and anxious cat, he does not trust to any cat or human other than me. He is always alarmed, just can't relax, and he rarely streches his body. Since his muscles are always tense, recently he's been having strong muscle aches, sometimes he can't walk and cry in pain. So in those times he has to get shots of pain killers but I don't want him to because his gastro-intestinal system is very sensitive also he has kidney and liver problems. A few times I smoke weed rolled with tobacco around him (this was years ago when I was ignorant now I never smoke anything around him) and in my suprise, he was very relaxed and smooth, his nose and paws were pink, he was really comfortable and he was stretching his body. So I thought, maybe I can smoke weed with a vapouriser near him every now and then and help him relax. But of course now I'm researching about this before trying and I wanted to know your experiences/knowledge/ideas. Also I came across something called Canna Companion, is there anyone who tried that, and do you think it helps with his anxiety problem?
