My 2.5 year old has always been immaculate when it comes to tidying up the litter box, until about a week ago. Now she has suddenly stopped covering up anything. My older cat never covers anything, but they have lived together now for over 2 years so that shouldn't be a new learned behavior. I did just take her to the vet Saturday before last for allergies and routine check-up (everything else checked out great) so it doesn't seem to be health related, unless it has something to do with the antihistamine she's now on. I don't see how an antihistamine would cause this change but who knows.
Any other ideas on why this sudden change? I should also mention that the litter and her box(es) have not changed in any way. Thanks!
