Sandie is right about what may cause blood to appear in your cat's feces. In addition to her sage advice regarding parasites and straining, you may be looking at FIP (feline infectious peritonitus), Feline IBD (Feline Inflammatory Bowel Disease), lymphosarcoma associated with FELV, the list is long and diagnosis can get very expensive quickly. Start with the most common cat diseases and go from there. If the condition is not disease related then you may consider the following.
Runny stools may be the result of a momentary dietary indiscretion, more often seen in kittens. Some cat breeders use plain, canned pumpkin (not the pie mix) to add roughage to the diet and firm up the stools. Ongoing diarrhea, when accompanied by vomiting, can indicate a more serious condition, and can cause dehydration. Excessive dehydration can have serious and sometimes deadly consequences for your cats.
Constipation is more likely with older house cats but not unknown in kittens. Their digestive and metabolic systems slow.The lower bowel may become "lazy" particularly in sedentary indoor cats. One or two extra-firm bowel movements might be a brief episode related to their diet or to stress, continued straining, or you observe your cat trying to defecate several times a day but being unsuccessful, means your cat should be seen by your veterinarian. Impacted stool can be very dangerous to your cat. Your vet may need remove the impacted fecal matter surgically or by hand. Petrolatum, laxatives, hairball remedies (they frequently contain white petrolatum in a palatable malt) and stool softeners may be prescribed
Make sure Peanut and Turbo have access to clean drinking water. If you have a large house you may want to put water in more than one location.
Encourage them to use the liter pan buy keeping it clean and tidy. Avoid cleaning the pan with harsh chemical. Warm water and a dye free perfume free dish soap are fine. Adding baking soda can give an extra measure of odor control.
If you are not comfortable with your veterinarian buy all means shop around. Most vets don't mind being interviewed and will take a few moments to speak with you. I also ask for a tour of the facilities the vet is using. If the place is unsightly or untidy or if you don't see adequate means for sterilizing surfaces, hands, and tools, etc; leave.....fast!!!! Ask the vet for the telephone number of his/her clients. Find out what they think and what they have experienced. Ask if he/she has ever been ensured or had his/her license revoked. Find out where the went to school, when, and ask how long they have practiced. Tip: ask if they are affiliated with any accredited national associations: AVA, AVMA, AAHA etc...
