So I went to Lowes garden dept today and asked the girl in that dept at the register if they ever sell any catnip plants? She says yes but only in warmer weather so I say, guess I'll go check and see if ya have any catnip seeds to sell here. So I come back w/ the seeds I found and there is another different girl there at the register and she looks at the seeds and says " are those for your cat?" and I say yes and she says"ya know those plants are bad for your cats as they can cause stomach ulcers and she suggests I go to Fred Meyers, which is a different store down the road aways and buy some stuff called wheat grass for cats instead. So I said ok then I guess I won't buy the catnip seeds. So Lowes just lost a sale and now I look on the internet and can't find a thing about cats getting ulcers from catnip. What I found was that even humans can drink a tea using catnip and it is supposed to be good for reflex or stomach problems. Anybody know anything about this stuff causing ulcers in cats?
