Cystitis in 11 year old lady

My cat is 11 & was recently unwell, we noticed she became clingy a few weeks before she started passing blood in her urine. She then became very lethargic & unsociable. We took her to the vets who ran blood tests & had a feel of her tummy. She then prescribed medication for cystitis, whilst we waited for the results we started her course of antibiotics.

A few days later she started to eat & drink again as normal & seemed to be getting over the worst of it. However, she now has another issue when doing a poop. She goes to the litter tray & starts doing what she needs, then before she finishes, she sort of sits down. This results in her taking some of her poop with her, which she then rubs all over our house..

Obviously, not great for us or her & I just wondered if anyone has had a similar experience or had any ideas on solutions.

She still isn't 100% but her blood tests returned normal. The vet has signed her off as fit, however I am a little worried about the secondary issue that seems to have followed on from the cystitis.

Thank u in advance for any advice..

Do you think she's constipated?  Not sure what that sitting down is, unless she's just wearing herself out straining.

Older cats ARE prone to constipation, especially if they have been fed dry food their entire lives.  What do you feed her?  Honestly, I haven't heard of a correlation between cystitis and bowel issues, but I'm sure anything is possible .  Did you  mention it to your Vet? 

Anyway, IF you think she could be constipated, there are a few things you can do:

1)  get her to take in more moisture.  You can do this be feeding her a wet diet (canned food) and adding water to that food, or following some of these tips:

2)  Adding in some pureed pumpkin to her diet.  Perhaps 1 teaspoon, up to 3 times a day, normally mixed into their wet food

3)  mixing Miralax into their wet food.  Between 1/8 and 1/4 teaspoon dissolved in a small amount of water (maybe a teaspoon).  It's entirely odorless and tasteless, so they don't even know it's there.  Plus it doesn't gel up so an extra bonus.  It mixes in very well.  I have used this for senior cats for years to keep them regular.  For us, we gave it twice a day, and night, and it worked like a charm.
