I have a newly adopted cat - she was previously an outside cat and I think she's at least 7-8 years old - but I really don't know. I noticed she was having loose stools for awhile and I attributed this to having been an outside cat. But after awhile (and after switching to a high quality food) I noticed her stools were not getting any better. Other than her stool, she acted fairly normal - she liked to play, sleep, eat, etc.
I took her to the vet thinking they could help me solve the stool issue. I trusted this vet because they were a sister vet hospital to the one I used to take my dog to. Anyway, they seemed busy that day... they quickly took my cat's temp, checked her over and assessed that she could use a "antibiotic shot" as well as some science diet i/d pet food to help her tummy. (Side note: I think Science Diet is more hype than help - and I believe vets are paid to "prescribe" it - but I'll save that post for another time!) Two mistakes happened though: 1) I had previously told the vet that my cat was 5 years old - so that was on her chart. After finding out a little more about her history, I told the vet I thought she was probably at least 8 years old... the vet didn't really seem to digest that info though or regard it as important. 2) I didn't question what the vet was giving her. I just trusted the vet without asking what the shot (Convenia) was. Dumb me.
My cat appeared to get a little better after that, but after a few days I noticed that she was sleeping more and playing less. She gradually kept doing this and I think she may have plateaued at this point. It has been 27 days since she received the shot. She does not play anymore. She sleeps all the time. She eats her i/d food and drinks but then goes right back to sleep. She won't jump up anywhere high and when I hold her on the couch with me she is soooo careful when she gets down. She also slowly walks up and down the steps. She just seems to have lost her love of life. BTW: I really don't believe that has anything to do with no longer being an outdoor cat. She was perfectly content to be inside and in her new digs before she got her Convenia shot.
I don't know what is going on. The vet didn't see anything wrong with her yet said the antibiotic shot would probably help any bacteria that might be upsetting her tummy. Her stool is since just ok - once and awhile it gets soft again. I am so afraid of bringing her to any vet - I have had a number of experiences that have made me not really trust vets. The last vet was one I thought I could trust. Oh, I also took a stool sample in to have it tested for parasites and the vet said she was all clear.
Long story short: I can't seem to find a lot of info supporting that side effects from Convenia last this long, but I cannot think as to what the issue may be. I'd be surprised if it was the food. I highly suspect it has something to do with the Convenia... any thoughts?
