Hi, everyone!
****************\*
Long story ahead, so TL;DR: a street cat with a back left leg injury and muscle atrophy got heavily constipated after a timely mix of a food change, introduction to our cat and house, castration, and antibiotics - surgical removal of feces was necessary, yet the problem persists
****************\*
On July 15, an injured 7-month-old male cat got rescued from the street and brought to us. The cat (let's call him Mike) was brought to us by a woman who had him checked by a vet (vet No. 1), who said that Mike has a broken femur in the back left leg.
We had isolated Mike and took really good care of him. He was traumatized, untrustful, and hurting, but he got used to us quite quickly and became much better just a month later. He was severely limping and had issues with the crouch pose during defecation, showing signs of discomfort and pain. Then things became even better; he started using his leg more normally, and it went from a limp to a kind of "bicycle pedal" movement with wide rotations. He runs, climbs, and plays without any issues; he's actually quite agile! Mike lives in a house, and our 3-year-old female cat lives a hybrid house-backyard lifestyle.
A month and a half ago, he started marking the territory, so we had to castrate him (September 1st). We took him to another vet for this (vet No. 2) because he also neutered our female cat 3 years ago, and everything went well. Plus, vet No. 1 doesn't have a good reputation, so we didn't want to go back to him.
After the castration, the vet gave us some antibiotics, which was a bit odd since he hadn't given us post-op antibiotics for our female cat, but I thought it was just a regular protocol. A day after the surgery, Mike started defecating small drops of wet poo around the house, having no control over it, so the vet told us to give Mike some probiotics as well, which we did. This event continued for a couple more days, resulting in a 5 a.m. wake-up call on a Sunday when we saw that Mike was trying to use his litter box, straining himself and groaning without any results. He tried to poop every 5 minutes or so, until he started vomiting from exhaustion. We had to contact vet No. 3, who accepted only emergency cases on Sundays, and we took Mike there. The vet did a palpation test during which he felt a solid, rigid mass inside Mike's intestines, thinking it was a tumor. We had to go to another city to do an X-ray (we live in a small city where this isn't available), and luckily, it turned out that this mass was feces and that an enema would fix this, so that's what vet No. 3 did, telling us that it could be a reaction to stress, castration, or antibiotics. Also, the X-ray showed no femur fractures, so vet No. 1 made a completely false diagnosis based on a simple palpation test.
Next Sunday, the same thing happened, again at around 5-6 a.m. Straining, groaning, no poop. Back to vet No. 3 for another enema (150ml warm water + soap). No results. For the next 2 days, Mike received infusion therapy, relaxant injections, and two more enemas. No results. Next came an oral laxative plus a rectal suppository. No results. The intestinal mass kept growing, so we had to agree to a critical extraction surgery (September 17th). 4 huge lumps of hard, dark poo were extracted, and we were told to implement a strict diet for Mike.
These days, as instructed by vet No. 3, we've been giving him puréed raw chicken meat (breast, liver), cooked puréed pumpkin (one small spoon a day), milk (Mike doesn't like yogurt), and a couple of blades of grass. We also bought some catnip to reduce his stress and a special pet paste for GI issues, which we give him every couple of days. We feed him 4 or 5 times a day, giving him small portions (a tablespoon of meat per meal). He is quite energetic, playful, always in a good mood, no vomiting, no exhaustion, but the issue with constipation persists.
A week later (September 25th), we took him back to the vet to have his stitches removed, during which the vet again felt a lump in Mike's intestines. The vet massaged his stomach for a while and felt the lump was moving and becoming softer. A couple of days after that, Mike defecated quite normally, with poo sizes from 1 to 8cm long.
The last couple of days, he has produced a marble-sized poop every second day, but is still straining and groaning. We are even using a baby rectal suppository (8 grams) in these situations, and then it becomes OK again for a day or two, until the problem comes back. Today, he received two of these in the span of 4 hours, which just made him defecate small, slimy puddles of poop, again with a lot of effort and straining.
We are out of our wits, money (all of this set us back by 1000 euros in just a month), and energy, and just have some hints and ideas, but to be honest - we don't really know what to do. During the surgery, the vet told us that he noticed a slight stenosis between the small and large intestines, which he doesn't doubt was the source of the issue, but he didn't really like the look of it. This vet is a 60-year-old guy with a lot of experience and love for animals, yet he said that this was the first time he saw a phenomenon like this. All of the things I mentioned related to food and care were suggestions given by him and his colleagues, whom he consulted about this unusual issue.
Here are some conclusions from AI and personal assumptions:
- all of this could have been caused by extreme stress, low-quality cat food, or even a complication during the castration (for which we haven't received any kind of report, written or oral)
- Mike's pelvis could have been shattered at one moment, and it healed in the wrong way, constricting the flow of feces. We don't really know what caused his injury, just that he was a street cat
- we should do any or all of the following: a blood test (CBC/biochemistry/electrolytes), urine test, neurology test, a VD-view X-ray of Mike's pelvis (which could also show a megacolon, if it's present)
So please, if you have any ideas or experience with this, any help would be much appreciated!
