My 8 month old girl is having some issues. It's been 4 days since she has defected. We recently started mixing adult food in with her kitten food. I thought that may be upsetting her stomach but now since its still going on Im getting worried. She is drinking water and eating. We've added some canned food and even a little canned pumpkin wich she really likes. She is urinating fine. Doesn't seem to be in pain but is a little lethargic. She still jumps up on the bed and plays a little but not alot. Once my vet opens this morning Im gonna see if he can see her today. Should I be worried about a blockage at this point? thanks for any info.
