Smokey is constipated and has been lying around sickly for 2 days..she travels back and forth to the litter box "trying" to go with no success...today she looked very weak...I decided to have a look down there and could see..."it was stuck"...I placed some vaseline on her butt to see if she could move it ...well that took awhile and it finally moved out...she's still the same way only a tad better...my question is besides hairballs what's causing this? and what can I use to clean up the area...it's a mess and smells bad...I'm afraid to use soap...she'll only lick it and get sick all over again...thanks for any help...
