one of my pigs who i thought had FINALLY outgrown the mouthy stage has recently begun grabbing my shirt with her teeth and pulling on it. i'm not really sure what it means or why she's doing it. she was an abnormally mouthy baby, and she's about 8ish month old now and it took forever to get her to stop nibbling on everything. she's a really affectionate piggy and loves to give piggy kisses, but this is just a weird behavior, at least one that i've never seen. should i be worried about something? or is she just be strange? and more importantly how to i get her to stop??
