Older Cat with Constipation

Hello and thank you kindly for offering your help.

My cat has not had a bowel movement in 5 days and is not eating more than a couple of bites per day. 2 weeks ago she was being cared for by a friend and was given too much dry food. Her stomach became enlarged so that she looked pregnant, but she continued eating normally and having bowel movements until the last few days.

She has been quiet and still, laying most of the time on a rug near the sink. When anyone comes by, she asks for water from the faucet and drinks a lot of cold water. She has fresh water in her bowl, but does not drink it.

At her dinner time, she asks for food, but does not eat much of the wet food she is given. I am not giving her dry food right now. Normally she has wet food as her main meal and a few bites of dry food if she needs a snack.

When she moves, she moves slowly, and when she lies down she seems to want to be curled up. She is happy lying curled on my lap, and she purrs when I pet her.

Normally, she is very talkative, even bossy, and somewhat restless, but since she's been constipated she is quiet and still.

She has not vomited and she is not crying. She does not seem to be straining in her box or really even trying to have a bowel movement. She is urinating regularly.

She is 15 years old. Over the last year, I have treated her for loss of bladder control when sleeping. Arsenicum has completely cured that problem. I give her one dose of Ars 30x (30c and 6c caused aggravations) every month or 2, when I see her coat become dry, and she has been quite well.

My use of the Remedy Finder suggested Arsenicum and Bryonia. I tried one dose of Ars 30x. Afterward, she took a big drink of water from the faucet and I heard gurgling from her abdomen and she seemed somewhat relieved, but there was no other progress. The next day I got some Bryonia 6c and tried one dose but saw no change at all. So today I have repeated the Ars 30x.

We will take her to the vet today if she does not have a bowel movement.

Could anyone suggest a better course of treatment?

Thank you very much.
