If your girl is constipated then you may be able to relieve this for your her by giving a teaspoon of cooking oil (olive oil) on her food once daily for the next week. You can also use a product called Microlax available from most drug stores, however you must be VERY careful when using this. This is a suppository that must be carefully inserted into your girls rectum using plenty of lubricant and then the product squeezed out. You would then notice she defecates within 10 - 15 minutes relieving any constipation. You may be a lot better off leaving your Vet to do this for your however.
If this is more of a longterm issue, then yes - feeding wet diets (pouches or cans) can definitely help, and encouraging water intake will help ensure the stool is of a normal consistency. To help encourage her to drink, make sure you have several water bowls around the house, and also consider buying a pet water fountain, as some cats prefer running water. Long term, you could also conisder a high fibre diet like Royal Canin fibre response. This is designed for cats with chronic constipation and help to moisten the stool as well as aid it's passage.
She may have cystitis- how would I be able to tell?
- she squats for ages and yesterday afternoon there was nothing at all solid or urine- just a little watery blood, (I know this because she went in the bath which she would never usually do as she goes outside). I have kept her in at the moment and will put down more water for her. What do you advise? I can't really afford the vet but I don't want to let her down
It WAS CYSTITIS, FLISS CAT NOW BEEN TO VETS AND IS NOW MUCH HAPPIER, THANK YOU
