I have had cats all my life, but my current pair of CPL-adopted kittens are genuinely the most destructive pair that I have ever come across! Gorgeous, but my word! They stand and carefully rip the inside of the table cloth to pieces, hang off the lamp shades, and rip any paperwork they can get their paws on.
One behavioural trait surprises me though: M, who is 7 months old, is obsessed with chewing cardboard. She takes tiny bites out of it, carefully spits that bit out, and then repeats, ad nauseam. She isn't bored, as she has her twin sister, plus there are always st least 2 devoted people playing with her all through the day. I don't mind this habit, and have developed ways of containing the mess (!), but just wondered what it was about? She must have all her adult teeth by now?
