Usually when a cat soils out of box, she is trying to communicate some type of distress to her human parents. The howling could indicate passing stools was painful. Bella may be slightly constipated.
Give her one to two ounces of whole milk. It is a natural laxative that will bring on a bowel movement within two hours.
If you prefer feeding her dry food instead of canned add salmon oil to keep her stool soft.
Sneezing is indicative of an upper respiratory infection or allergy.
She can have an antihistamine for either.
You can add one quarter of a 4 mg chlortrimeten to a tablespoon of baby food chicken or turkey with no onion or garlic.
Give it every 24 hours. It is very tiny so she will not detect it
Any of these are also acceptable:
Benadryl at a dose of 1/2 of a 25 mg tablet given twice daily or
Chlorpheniramine at a dose of 2-4 mg twice a day or
Claritin (Loratadine) at a dose of 2.5-5 mg/cat or
Zyrtec (cetirizine) 5 mg once or twice a day
It is important to ensure that the formulations used contain ONLY the antihistamine and are not combination products (e.g. Claritin-D contains pseudoephedrine, which could cause very significant adverse effects in a cat).
Please let me know how she is doing. Just reply here or if you prefer, we can speak on the phone.
