My cat ate a piece of string (not a thick one. A slim one used for sewing). She passed it through her mouth and seeing her struggle I did the stupid thing of pulling on it because I panicked. I pulled very gently, after she eliminated a ball of string, and I encountered no resistance while pulling. She stood still while I pulled, except for the last centimeters of string. The string I pulled was straight, with no knots.
After this, she vomited 2-3 times a clear liquid, sometimes foamy. She seemed to have no changes in behaviour other than not eating as much as usual.
I had to leave the house for some time for work, and came back home at 2 am, 8 hours after last seeing her. She vomited once more after I arrived,but she looks tired (it's still 2 am). I found no other vomit puddles. There is no vet opened at this hour but I'll get her to one first thing in the morning.
Is there anything I should know until sunrise?
