Well, Mittens doesn't have intestinal cancer. The vet gave her an ultrasound on Tuesday and didn't see any masses whatsoever, and he didn't do any further testing aside from whatever the geriatric exam involves (my mom had to go to work, so she wasn't there for that). He said that the sheer amount of constipation Mittens had endured probably gave the appearance of intestinal masses when she was X-rayed. Mom was given some special food and stool softener to feed Mittens. I'm home for Thanksgiving weekend so I got to see how Mittens is now. This is a bit long, but I wanted to give an accurate picture of what's going on.
She got a second dose of anesthesia on Tuesday, so I'm not sure how much of this can still be attributed to that and how much is a sign of an actual problem- but Mittens definitely isn't herself. She seems to not be willing/able to do much with her back legs except walk. Her walking looks normal, but she didn't jump up to anything the entire time I was home, and she's very wary of jumping down from the couch or anything if one of us puts her on it. She leans off the couch and puts her front legs down the side of the couch, as if she's going to push off, but then she backs off and just stays up there. When we hold her, she is afraid to be put down and clings to us. I think she's scared she's going to fall, and she's probably right.
She also isn't cleaning her back half, so I had to clean her myself a couple times, and she isn't scratching her ears (normally when I scratch behind her ears she starts scratching herself). She is bathing her front half normally, and she still loves to eat. Using the litter is still a chore for her, but she has been using it once or twice a day.
Otherwise, she seems like a very slow version of Mittens. She keeps randomly walking up behind us, so we've had to be very careful not to step on her - the vet did say the anesthesia would cause this, so that's not so much of a concern. I tried playing with her today, with a piece of string, and she didn't know how to go about chasing it. She walked after it (I took her on a couple slow laps around the house), but when she got up to it she would walk over it and look around. I gave her a toy rubbed in catnip while she was lying down, and she just put her front leg over it. When I carry her around, she doesn't sniff things I hold her up to like she always did. She does, however, still happily lick my face, she purrs when Mom holds her, and she sniffs Toonces when she goes up to him. Toonces jumped on her a couple days ago and she hissed, which was normal. Otherwise, Toonces has left her alone.
So I'm not sure how to interpret all this. Can the anesthesia possibly cause all this to happen - and, if so, will it wear off or has Mittens been permanently affected? It's been since Tuesday since she got it, and now it's Monday. I would say she has improved slowly since I got home - Thursday she would hardly move and was very limp, but she is definitely walking around more now. She is a fat cat, about 15 pounds when weighed at the vet, so that is part of the consideration for how long it would take for two doses of anesthesia to fully wear off.
I've told my mom that if Mittens doesn't keep improving over the next few days to take her back in, but if any of you have experienced anything similar to this I would appreciate any insight.
