My cat hasn't pooped in 2 days. When to worry about constipation?

Hi! My kitty hasn’t gone number 2 In roughly 48 hours or so.. which isn’t typical for him. He did this once b4 a couple of weeks ago and then went back to normal until now. At what point should I be concerned? All other behavior is normal. He started a new hills rx canned food on November 19th.. that’s been the only recent change. Thx!!

I would not necessarily be concerned at this point if Tony is acting normally in every other way. The only thing I would add is probiotic. I like Fortiflora but you can use any probiotic made for cats (no human products and no dairy). http://www.allivet.com/p-1890-purina-pro-plan-veterinary-diets-fortiflora-cat-supplement-box-of-30.aspx This won't hurt anything and may help get him more "regular". Hope this helps. Best wishes.
